Began working on a function to make creating list items easier. The
main function is defined in Item.js but is accessed through
SP.createItem()

TODO:

1. Complete createItem function
2. Integrate testing plans:
	a. Unit testing
	b. Midway testing
	c. End-to-End testing
	d. This will be done using a popular and robust testing framework
	(Mocha.js). Mocha has a browser based framework (great for testing
	on SharePoint) but it would require a lot of excess code in the
	development code, and a ton of cleaning when moving to production.
	I propose a Grunt plugin that will strip away all of the test code
	and even shut down/turn on all tests of a certain type (eg. grunt
	mocha-test:unit --all-on would activate all unit tests)
