Express like path handling method for Go. Path: "/user/:name/dashboard/stats/:range/", here "name" & "range" are params which are accessed within the "request" object of Express router handler.

Basic Idea : The function receives 'path' that will be handled by the server and the 'url' the request was sent to/from. It will split the 'path' into all the params and parse's and finds those params which has ":" at the beginning. It will also split the 'url' into all the params that were sent from server. A loop, loops over all the elements inside the splitted 'path' (here, path_list), finds the position where ":" is present in a element of path, removes the ":", creates key of with that element, and sets value of the key from the splitted 'url' (here, url_list) at the same index position. Makes a map of key-value pairs, returns it, with a boolean of whether the 'path' and 'url' are a match.

// path : the path the `url` will be mathced with
// url : the url the request was sent/received to/from server
func handlePath(path string, url string) (bool, map[string]string) {
