+ * Template render engine.

+ * @package phpLDAPadmin
+ * @subpackage Page

+
+/**
+The template engine has the following responsibilities:
+* If we are passed a DN, then we are editing an existing entry
+* If we are not passed a DN, then we are passed a container (and creating a new entry in that container)
+
+In both cases, we are optionally passed a template ID. 
+* If we have a template ID, then we'll render the creation/editing using that template
+* If we are not passed a template ID, then we'll either:
+	* Present a list of available templates,
+	* Present the default template, because there are non available (due to hidden,regexp or non-existant)
+	* Present the only template, if there is only one.
+
+Creating and editing entries use two objects:
+* A template object which describes how the template should be rendered (and what values should asked for, etc)
+* A page object, which is responsible for actually sending out the HTML to the browser.
+
+So:
+* we init a new TemplateRender object
+* we init a new Template object
+* set the DN or container on the template object
+	* If setting the DN, this in turn should read the "old values" from the LDAP server
+* If we are not on the first page (ie: 2nd, 3rd, 4th step, etc), we should accept the post values that we have obtained thus far
+
+* Finally submit the update to "update_confirm", or the create to "create", when complete.
