/******** Change Log ***************
Date: 3-Jun-2011
Author: Jedediah Holller
Notes:
Added in check to determine whether jQuery is already loaded.
Previously, it would load a copy of jQuery whether it had already been loaded or not,
which would cause errors. Now, if jQuery has already been loaded, then it will skip loading
