/**
* A Class to hold Service "ContentTypes", and to match incoming "Accept" types from HTTP.
- *
+ *
* This is a multi-use class built to use the same Parser for ContentTypes and Accept.
- *
+ *
* Thus, you would create and use "Content.Type" within your service, and use it to match
* Accept Strings. What is returned is an Integer (for faster processing), which can be
* used in a switch statement to act on match different Actions. The server should
* know which behaviors match.
- *
+ *
* "bestMatch" returns an integer for the best match, or -1 if no matches.
