#Backend: Implement a router method for parsing URL path parameters

[ComputerGeek5]

We need to add a method in core/Router.php for parsing URL path parameters like /users/{id}. We will need this functionality if we want to view single resources (NOT list all of them) both in our front end and in the API.

@ComputerGeek5 This issue should be in the backlog because I already defined the API structure on Issue #36. I think we should take a look at this later.

This can be simplified using .httacess.
