Added a taglib which allows the specification of a variable name and model class such that the variable can be accessed from jstl taglibs and expressions.  e.g.

<%@taglib prefix="acq" uri="http://activecq.com/wcm/taglibs/activecqtags/1.0"%><%
%>
<acq:init var="model" model="com.day.cq.wcm.apps.geometrixx.GeometrixxTextComponent"></acq:init>
${model.text}
