walk VF module names

walk VF module names

Added code to walk the VF modules to count the number of modules and
to generate the new module instance name.
Added comment to test method.
Fix checkstyle errors.
Read json files instead of resources.
Removed checkstyle plugin from aai pom, as it continues to barf every
time I use some automated feature of Eclipse.
Use Files.readAllBytes() instead of IoUtils.toString(uri).
Try concatenating file path.
Turned out to be a problem with file name case sensitivity - renamed
the file.
