new RgbLightfield class in illum
rgblearn command implemented in prototype
prototype color input. compiles, no runtime errors, no good output yet.
now successfully corrects RGB images in proof of concept,
including saving and loading RGB lightmaps.
results don't look good yet but they're no longer blank.
so:
fix for #1
fix for #2
will open new issues for bad output
this isn't working at the moment, but it at least is factored right.
color parameter now handled properly. learning works.
correction is still broken because it demosaics, etc.
compiles, split correct into gray_correct and color_correct.
not tested.
works. output looks like channels aren't in the right order, or something
like that.
nasty typo where color channels were in the wrong order.
removed debug prints
now smooths in RGB correct mode
clarified bayer pattern params in usage
Merge pull request #13 from joefutrelle/color
