GLM colortables

As forecasters begin to look at the gridded events from GLM, we have provided them with multiple color curves to examine the data.  From the first couple weeks of feedback, it appears that different user needs and personal preference are the primary driver for different color curves.  (Note the default gridded data option in AWIPS/CAVE is NOT included here... that color curve is horrible).

For a baseline comparison, below I'm including the four different colortables available for forecasters today using activity over the southeastern United States.  Note the different appearance whether or not interpolation is chosen for the display as well.
