Initial commit
Implemented accept and accepts functions
Modifying the accepts function to use a map

Previously the accepts function took a list of media types and a function that
took the expected type as an argument.  Because MediaType are difficult to match
against, it is easier to work with an ordered list instead.
Adding description, bumping versions
