 * created in the workbench with the given perspective.

 * The visible perspectives within the menu may also be updated dynamically to
 * reflect user preference.

 * The input for the page is determined by the value of <code>pageInput</code>.
 * The input should be passed into the constructor of this class or set using
 * the <code>setPageInput</code> method.
