 * UriTemplateMatcher allows matching based on uri templates.

 * Examples of several uri templates types are below:

 * Variable: /foo/bar/{var}

 *    Will match any path that starts with /foo/bar and has one additional segment

 * Literal: /foo/bar/goo

 *    Will match only a path of /foo/bar/goo
