First attempt to add the color tables of Hinode/SOT.
For now it just includes the red color table used for intensity, however
it's still missing covering the cases of other types like Stokes and
magnetic field.  A template has been added.
moved SOT properties into the hinode.py file
removed sot.py file
Merge pull request #3 from dpshelio/SOTMap
