Turn a generic message descriptor into a loading schema for a pig script.  Individual fields that are enums
are converted into their string equivalents.
@param msgDescriptor the descriptor for the given message type.
@param numTabs the tab depth at the current point in the recursion, for pretty printing.
@return a pig schema representing the message.
