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