Created September 24, 2013 01:05

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

	/**
	* A jquery plugin wrapper for a pure JavaScript class
	*
	* This will automatically give us the following:
	*
	* - a constructor for our class using $('my.selector').myClass()
	* - automatic method access to the class's instance functions via syntax
	* $('my.selector').myClass('funcName', arg1, arg2, ...argN);
	* - automatic property access of all the class's internal properties. Both this
	* and the above can assist greatly with third-party code integration
