Implement CIE X and Z integrals
Dump output for SkyRender (single slice)
Add path concatenation to BufferedWriter
Read output directory from args
Add gitignore to ColorArray
Replace ColorArray with SkyRender for single patch
Remove bounding box statistics
Support SkyRender version of mags2temp
Clean up mags2temp source

Program is now dedicated to computing black-body temperatures and
amplitudes from J,H,Ks fluxes and errors while passing along coordinates
for successful fits.  File output is now handled directly rather than
relying on a later pipeline stage (since the output is now binary,
compression is no longer needed).
Render all-sky images from multiple patches
Avoid unnecessary rebuilds

Using targets to create 'bin/' and 'build/' directories led to
wasteful recompilations.
Rename ColorArray to SkyRender

While the ColorArray kernels remain, they are no longer called by the
driver.
