- * A Class to hold Service "ContentTypes", and to match incoming "Accept" types from HTTP.\r

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