Set up global variables and configuration for the RTM widget

@see https://cloudup.com/cySVQ9R_O6S for the standard setup instructions
function configureGlobals() {
	// Set up the global DirectlyRTM function, required for the RTM widget.
	// This snippet is pasted from Directly's setup code.
	window.DirectlyRTM =
		window.DirectlyRTM ||
		function() {
			( window.DirectlyRTM.cq = window.DirectlyRTM.cq || [] ).push( arguments );
		};
	// Since we can only configure once per pageload, this library only provides a
	// single global configuration.
	window.DirectlyRTM( 'config', getDefaultOptions() );
