/*GETTING INFORMATION BACK ABOUT A SPECIFIC ATTRACTION
The best way to get text for an attraction:
Search for [articles/entries] in category you're attraction is in. Loop through the results and match titles with the desired title.
Blocks with the role 'catalogue' or 'listing_entry' have the text in the top level of the response.
Blocks with the rold 'star_sight' will have text inside an intro block.
All text will have key of 'p'. Stripping out HTML from the text is advisable as there are some scenarios where certain HTML tags are used.
Any blocks with the role 'dir_entry' do not have any text associated with that attraction.
Finding images is best done in a similar fashion. Search the category for illustrations and then match titles with the attraction you are looking for.
