 *
 *
 * 2. Generic Blog Widget Type config
 * Paramteres priorities are order according to their level of specificity
 * e.g. DOM node id - defines an element unambiguously - according to the html specification particular id should appear
 * only once in the html document, while class/tag may be used with numerous elements in the same document.
 * When id and class are both defined for the same element type - the id should always be used over the class
 * as an element indicator.
 *
 * 2.1 Posts Detection
 * -> Often time whole content section is contained in some sort of wrapper. It separates the blog content from headers,
 * -> footers and side pannels.

 * -> the blog platform.
 *
 * listonic_bw_generic_entryClass - css class of the single entry wrapper
 * listonic_bw_generic_entryTag - tag of the single entry wrapper
 *
 * 2.2 Post Processing

 * -> Following parameters define the header element
 *
 * listonic_bw_generic_entryHeaderClass - css class of the header wrapper
 * listonic_bw_generic_entryHeaderTag - tag of the header wrapper
 *
 * -> Parameters indicating entry title.
 *
 * listonic_bw_generic_entryHeaderTitleClass - css class of the entry title

 * listonic_bw_generic_entryHeaderUrlWrapperTag - ta of the url wrapper
 *
 * listonic_bw_generic_entryHeaderUrlClass - css class of the url tag is always <A>
 *											 when no class provided search by tag is applied
 *
 * 2.2.3 Post Footer
 * -> Post footer may contain some specific information about post we would like to extract.
 * -> E.g. tags, url ...
 * -> Following paramerts define the footer element
 *
 * listonic_bw_generic_entryFooterClass - css class of the footer wrapper
 * listonic_bw_generic_entryFooterTag - tag of the footer wrapper
 *
 * //use only when not defined in the header
 *
 * listonic_bw_generic_entryFooterUrlWrapperClass - css class of the url wrapper
 * listonic_bw_generic_entryFooterUrlWrapperTag - tag of the url wrapper
 *
 * listonic_bw_generic_entryFooterUrlClass - css class of the url tag is always <A>
 *											 when no class provided search by tag is applied
 *
 *
 * 2.3 Other
 *
 * listonic_bw_generic_validateULs - function applied to the ULs found in the post.
 * @return true - when ul is valid ingredients list, false when ul is not valid ingredients list
 * E.g. moje wypieki blog.
 *
 * listonic_bw_generic_getTags - custom function to extract tags for entry
 * @return array of tags

/**
 * BlogWidget Configuration
 * 1. Global ustawienia widgeta
 *
 * listonic_turnOff = true/false - włącza lub wyłącza przyciski
 *
 * listonic_bw_type - typ widgeta {blogger, blox, bloog, generic} - deklaracja platformy blogowej pozwala na używanie predifionwanych ustawień
 *
 * listonic_includeTags - array of tags, widget procesuje jedynie posty oznaczone co najmniej jeden z wymienionych tagów
 * listonic_excludeTags - array of tags, widget nie procesuje postów oznaczonych co najmniej jednym z wymienionych tagów
 * listonic_firstOnly - boolean, aka listonic_tylkoPierwszy - jeśli true tylko pierwszy <ul> w danym poście jest przetwarzany
 * listonic_minCount - integer, aka listonic_tylkoPierwszy - minimalna ilość elementów w liście <ul> dla której dodawny jest przycisk, default = 3
 * listonic_iframeWidth - szerokośc widgetu w panelu bocznym
 * listonic_hideSideBar - boolean - aka listonic_ukryjPanelBoczny - jeśli true nie generuj widgetu w panelu bocznym 
 *
 *
 * 2. Konfiguracja widgeta w trybie pracy GENERIC
 * Prioryteyzacja parametrów zgodna jest z dokładnością definiowanych przez nie elemnety
 * n.p. DOM node id - wskazuje element jednoznacznie - zgodnie ze specyfikacją HTML w dokumencie powinien znajdować się dokładnie jeden 
 * element o określonym id, elementy określane przez class/tag mogą wsytępować wielokrotnie w całym dokumencie
 * Gdy dla wskazania danego rodzaju elementów zdefiniowane są zarówno id or class/tag wówczas element wskazany przez id zostanie 
 * użyty dla celów procesowania.
 *
 * 2.1 Wykrywanie Postów/Wpisów
 * -> Bardzo często treść bloga opakowana jest w jeden element DOM, dzięki czemy może zostać skutecznie odseparowany od 
 * -> headerów, footerów czy sidebarów. 
 * -> Korzystając z tego możemy zawęzić obszar procesowania, unikając umieszczania przycisku w nieodpowiedniej sekcji.
 *
 * listonic_bw_generic_contentId - id głównej kolumny z treścią - zawierającej wszystkie wpisy
 * listonic_bw_generic_contentClass - klasa wskazująca główną kolumnę //TODO: implement
 * listonic_bw_generic_contentTag - tag kolumny głównej //TODO: implement
 *
 *
 * listonic_bw_generic_contentAsEntry - (default=false) - treat main column content as the whole entry
 *		comment - used in one case for a single entry view (single entry on page,without a further structure inside)
 *
 * -> Poniższe patametry definiują element opakowujący pojedynczy wpis. Najczęściej zawiera w sobie header wpisu, footer wpisu 
 * -> w zależności od platfromy blogowej.
 *
 * listonic_bw_generic_entryClass - klasa wskazująca element opakowujący pojedynczy wpis
 * listonic_bw_generic_entryTag - tag elementu opakowującego pojedynczy wpis
 *
 * 2.2 Przetwarzanie Postów/Wpisów
 * 2.2.1 Treść Wpisu
 * -> Poniższy pametr pozwala na wskazanie treści wpisu wewnątrz elementu opakowującego.  
 * -> Jeśli nie jest zdefiniowany wówczas cała zawartość wprapper jest procesowana jako treść wpisu.
 *
 * listonic_bw_generic_entryContentClass - klasa elementu zawierającego treść wpisu 
 * listonic_bw_generic_entryContentTag - tag elementu zawierającego treść wpisu
 *
 * 2.2.2 Header Wpisu
 * -> Nagłówki wpisu często zawierają informacje o tytule, adresie url itp. które chcemy wydobyć
 *
 * listonic_bw_generic_entryHeaderClass - klasa nagówka wpisu
 * listonic_bw_generic_entryHeaderTag - tag nagłówka wpisu
 *
 * -> Poniższe parametry pozwalają na wskzanie elementu zaiwerającego tytuł wpisu
 *
 * listonic_bw_generic_entryHeaderTitleClass - klasa elementu zawierającego tytuł wpisu
 * listonic_bw_generic_entryHeaderTitleTag - tag elementu zawierającego tytuł wpisu
 *
 * -> Pniższe patametry definiują element zawierający adres URL - najlepiej aby prowadził on do widoku pojedynczego wpisu
 *
 * listonic_bw_generic_entryHeaderUrlWrapperClass - klasa wskazująca na wraper adresu
 * listonic_bw_generic_entryHeaderUrlWrapperTag - tag wskazujący na wraper adresu
 *
 * listonic_bw_generic_entryHeaderUrlClass - klasa elementu zawierającego adres url wpisu tag to zawsze <A>
 *											 jeśli klasa nie jest zdefiniowana wówczas następuje wyszukiwanie po samym tagu
 *
 * 2.2.3 Post Footer
 * -> Stoka wpisu często zawiera informacje które chcielibyśmy wydobyć n.p. tagi, adres url
 *
 * listonic_bw_generic_entryFooterClass - klasa stopki wpisu
 * listonic_bw_generic_entryFooterTag - tag stopki wpisu
 *
 * //poniższe parametry są używane jedynie gdy odpowiadające parametry nie zostały zdefiniowane dla nagłówka
 *
 * listonic_bw_generic_entryFooterUrlWrapperClass - klasa wskazująca na wraper adresu
 * listonic_bw_generic_entryFooterUrlWrapperTag - tag wskazujący na wraper adresu
 *
 * listonic_bw_generic_entryFooterUrlClass - klasa elementu zawierającego adres url wpisu tag to zawsze <A>
 *											 jeśli klasa nie jest zdefiniowana wówczas następuje wyszukiwanie po samym tagu
 *
 *
 * 2.3 Other
 *
 * listonic_bw_generic_validateULs - funkcja wywoływana dla celu zwalidownia poprawności znalezionych elementów <ul> we wpisie
 * @return true - gdy ul zawiera składniki przepisu, false gdy ul nie zawiera składników przepisu (wyrzucany jest z dalszego przetwarzania)
 * E.g. moje wypieki blog.
