A node-red node for parsing pathparams in routes for RESTful Web Services.

Parse out pathparams from the route and return in an associative array.

Associative Array is stored in msg.req.route.params as key value pairs.

If the route was defined in a HTTP input node as:

/api/test/:lastname/:firstname/anything/:else/you/might/:route

and the actual request path is:

/api/test/Hill/Mike/anything/foo/you/might/bar

the parser would add key/value pairs based on path parameters that start with ":" in msg.req.route.params:

msg.req.route.params = {
    lastname : "Hill",
    firstname : "Mike",
    else : "foo",
    route : "bar"
}
