debug build for Maria about maria HOT 5 CLOSED

I like something like debug. I have had great success with opt in debug information by setting flags in localStorage.

If a View template is parsed and has more than one top level element in the DOM fragment, then console.warn as that is likely an error.

If a view is automatically instantiating a controller yet the controller file has not even been loaded then make a more specific error saying that particular controller constructor function cannot be found and include the expected controller name in the error message.

If a view cannot locate a template (e.g. the template file is not loaded or the template is misnamed) then the error message is cryptic. Something about str is null when calling trim.

The debugging builds are created and the messages mentioned in this ticket are implemented. The plan is to add more debugging messages over time as new message possibilities are discovered but everything in this ticket is completed.
