Boilerplate code for wrapping up a JavaScript object / class into a jQuery plugin

	* A jquery plugin wrapper for a pure JavaScript class

	* - automatic method access to the class's instance functions via syntax
	* $('my.selector').myClass('funcName', arg1, arg2, ...argN);

	* and the above can assist greatly with third-party code integration
