Implemented mechanism to simulate HTTP requests when running from the command line:
	This is achieved by calling the app with the following parameters:
		php index.php --simulate-request request.json
	Below is an example of what the contents of the file should look like:
		{
			"get" : {
			},

			"server" : {
				"REQUEST_METHOD" : "GET",
				"REQUEST_URI" : "/"
			},

			"contents-file" : "file/path"
		}
Fixed various bugs with the system
