// MethodOverride is the default implementation for the
// Options#MethodOverride. By default it will look for a form value
// name `_method` and change the request method if that is
// present and the original request is of type "POST". This is
// added automatically when using `New` Buffalo, unless
// an alternative is defined in the Options.
