#search_in_known_locations(filepath, additional_search_paths = []) ⇒ Object Also known as: find_file

Searches for filepath in the searchable_paths iff filepath doesn’t exist. e.g. filepath is interpreted first as an absolute path, if filepath doesn’t exist verbatim then it looks for the file in the searchable_paths.

Returns nil if the file cannot be found.
