Adding a template processing example

This example shows how templates can be searched, updated, processed,
and applied to the cluster.  This initial commit will fail because of
a bug that @psolarvi found and will fix once PR #67 merges.

+This example will scan all the templates, on the cluster, and look specifically for the openshift/nginx-example
+template.  If the template is located, it clears the namespace (to prevent an error when calling 'oc process'),
+updates any template parameter(s), processes the template, and then creates the objects in the current namespace.
