# GempakGridLinkRequest
#
# This code has been developed by the SIB for use in the AWIPS2 system.
# Performs a BaseRequest for a grid data from GEMPAK, and stores
# the float data in the uEngineProducts directory for later transfer.
#
# Usage:
# import GempakGridLinkRequest
# dataRequest = GempakGridLinkRequest.GempakGridLinkRequest("grib")
# dataRequest.setDataUri("...")
# return dataRequest.execute()
