URL Pattern Parser

	// We need to write a function in JavaScript that parses all the variable parts of a
	// url, and any url parameters, into a hash. The function should take two arguments:
	// 1. A "url format" string, which describes the format of a url that can contain
	// constant parts and variable parts (where "parts" of a url are separated with "/").
	// All variable parts begin with a colon. Here is an example "url format" string:
	// "/v6/:collecton/:id"
	// 2. The second argument is a particular url that is guaranteed to have the format
	// specified by the first argument. It may also contain url parameters. For instance,
	// given the example url format string above, the second argument might be:
	// "/v6/photos/3?size=large&res=high
