+Steps to implement SimpleView template:
+-in template-params.xml.ftl:
+    -add the following line to common imports
+        <common src="activities"/>
+
+-Add a Fragment to handle behavior.  In your MainActivity.java class, it will reference a Fragment
+ called (yourProjectName)Fragment.java.  Create that file in your project, using the "main" source
+ folder instead of "common" or "templates".
+   For instance, if your package name is com.example.foo, create the file
+   src/main/java/com/example/foo/FooFragment.java
+
+-refer to sampleSamples/simpleViewSample for a reference implementation of a
+project built on this template.
