/**
* This Load/Store Func reads/writes metafiles that allow the schema and
* aliases to be determined at load time, saving one from having to manually
* enter schemas for pig-generated datasets.
*
* It also creates a ".pig_headers" file that simply lists the delimited aliases.
* This is intended to make export to tools that can read files with header
* lines easier (just cat the header to your data).
* @deprecated Use PigStorage with a -schema option instead
