# GempakMcidasHdrRequest
#
# This code has been developed by the SIB for use in the AWIPS2 system.
# Performs a BaseRequest for a McIDAS "image header" from GEMPAK.
#
# Usage:
# import GempakMcidasHdrRequest
# dataRequest = GempakMcidasHdrRequest.GempakMcidasHdrRequest()
# dataRequest.setImageType("...")
# dataRequest.setAreaName("...")
# dataRequest.setResolution("...")
# dataRequest.setTime("...")
# return dataRequest.execute()
