Ant-style path patterns

AntPathMatcher.txt

Part of this mapping code has been kindly borrowed from Apache Ant.

The mapping matches URLs using the following rules:
? matches one character
* matches zero or more characters
** matches zero or more directories in a path
{spring:[a-z]+} matches the regexp [a-z]+ as a path variable named "spring"
Examples

com/t?st.jsp — matches com/test.jsp but also com/tast.jsp or com/txst.jsp
com/*.jsp — matches all .jsp files in the com directory
com/**/test.jsp — matches all test.jsp files underneath the com path
org/springframework/**/*.jsp — matches all .jsp files underneath the org/springframework path
org/**/servlet/bla.jsp — matches org/springframework/servlet/bla.jsp but also org/springframework/testing/servlet/bla.jsp and org/servlet/bla.jsp
com/{filename:\\w+}.jsp will match com/test.jsp and assign the value test to the filename variable
