/** Ipsum je veřejná třída, která obsahuje
dvě pole řetězců - stringů.
Pole Headlines slouží jako uložiště pro názvy, které
budou načteny do ListView - seznamu v HeadlinesFragment.java
Pole Articles je v našem případě zásobárnou článků, které
budou načteny dle pozice položky ListView předané z HeadlinesFragment
zoětbě do MainActivity a
odtud do ArticleFragment.java, jako parametr metody
articleFrag.updateArticleView(position);
nebo jako argument Bundle
Bundle args = new Bundle();
    args.putInt(ArticleFragment.ARG_POSITION, position);
	
Stringy - ukládat do souboru java je ošemetné (problémy s kódováním, vyhledávání výrazů atd.) 
U většího množství článků pak nepřehledné.
Navíc, uživatel nemůže tento text editovat.
K ukládaní většího množství dat, k jejich vyhledávání 
a editaci je lépe používat databáze.
