Initial release.
Factored much code into seperate classes, available seperately in RFID::Base and RFID::EPC. These changes should allow different readers to be addressed with roughly the same interface, much like accessing different databases with DBI drivers.
Fix incorrect timeout units in reader modules.
alien.pl: Add -r "restart" option to automatically re-connect on error.
Add -q "quiet" option to suppress all output except ISEE messages.
