// Pattern represents a compiled pattern. It is what is returned
// from calling either the Compile to MustCompile funcs.
//
// Pattern provides the Match, FindAndLoad, and MatchNames methods.
//
// Example Usage:
//
// pattern, err := pathmath.Compile("/users/{user_id}")
// if nil != err {
// fmt.Printf("ERROR Compiling: %v\n", err)
// return
// }
//
// var userId string
//
// didMatch, err := pattern.Find("/users/123", userId)
// if nil != err {
// fmt.Printf("ERROR Matching: %v\n", err)
// return
// }
//
// if didMatch {
// fmt.Printf("user_id = %q\n", userId)
// } else {
// fmt.Println("Did not match.")
// }
