added an examples and demo file to show parser functionality. There is a slight flaw in the current code. The current code assumes that there are <a></a> tags wrapping each ingredient, however this is only true for ingredients with associated hyperlinks, if an ingredient does not have an associated hyperlink, then it is only wrapped in a <span></span> tag, further tweaking of ingredient parser needed.
Fixed issue with getIngredients. getIngredients can now handle ingredients that have associated links as well as ingredients that do not.
