MustNewEvaluatorFromRegexp same as NewEvaluatorFromRegexp but it panics on the "expr" parse failure.

NewEvaluatorFromRegexp accepts a regexp "expr" expression and returns an EvaluatorFunc based on that regexp.

NewMap returns a new macro Map with default type evaluators.

Parse takes a full route path and a macro map (macro map contains the macro types with their registered param functions) and returns a new Template.

Map contains the default macros mapped to their types.

Template contains a route's path full parsed template.

TemplateParam is the parsed macro parameter's template they are being used to describe the param's syntax result.

EvaluatorFunc is the signature for both param types and param funcs.
