Added documentation primarily for building the man pages locally
There is a requirement for pod2rst
Modified the create_man_pages script to allow for local perl
module path
Check in the initial pages that are generated from the pods
Once these are in, will look into how to autopush changes from the xCAT build scripts
when POD files are changed. This seems to be the quickest way to get the man pages
into the documentaion at this point.
