PHP API Server: Route requests to API calls to handler classes

This class can route requests to API calls to handler classes.

It takes as parameters the name of an API call being invoked by a client via HTTP and an array of request parameters.

If the called API function is named Describe, the router class loads a class named Describe from the API directory path and makes the request be handled by that class.

For other API calls, the name of the call up to the / character defines the class that will handle the API call.

The name in front of the first / character defines the API call function name that is invoked on the API call handler class.

The router class checks first if a class file exists with that class name and loads it in that case. The router class also checks if the handler class also has a function with the invoked name before calling that handler class function.

API call error responses are returned in JSON encoded format.
