/**
* Helper class from which all Jsp Fragment helper classes extend.
* This class allows for the emulation of numerous fragments within
* a single class, which in turn reduces the load on the class loader
* since there are potentially many JspFragments in a single page.
*
* The class also provides various utility methods for JspFragment
* implementations.
