Description

MAPL3 needs a mechanism to accumulate field data for output. Accumulation includes mean, min, and max functions on the field. This PR implements that mechanism for ESMF_TYPEKIND_R4 fields for the mean and max functions. The core accumulation procedures are tested, and the procedures for the mean have received basic testing. Later PR's will implement the mechanism for ESMF_TYPEKIND_R8 fields, implement the min function, and test all the procedures more extensively with necessary bug fixes.
