Release Notes: This release adds an "ungrid" commandline utility to extract points from a gridded binary file. The commandline utilities have been extended to allow saving the number of points contributing to each of the binned values ("irregrid") and to support C "float"-type formatted binary files ("regrid"). The forward and inverse functions now perform a self-test by calling each other once and comparing the results. The build system now generates position-independent (-fPIC) code by default. The .gpd and .mpp files have been updated. Minor fixes and clean-ups have been added.
