[Req] Add a method to debug

[jmtucu]

I love this profiler and the unique thing I really miss is a debugger for variables.

Maybe you can create a method like this

<?php Profiler::debugVar('var_name', $var); ?>

And display in the result a table like this

var_name | value of the var

Just an idea :)

Love the idea!
I'd expand the idea to adding a message like printf works. It should be as easy as the debug option.

If I'll find some time for it I'll do it and create a pull request.
