/*
	jQuery Clear-Input plugin
	v1.0
	Author: Aidan Feldman

	USAGE
	Add the class .clear-input to any text input element
	whose value you want cleared when it gains focus.
	The initial value will be replaced when the input
	loses focus, and no new text has been entered.

	If you prefer to not add classes to your elements,
	you can alternatively call clearInput() on any jQuery
	input object.
