3D multi-wavelength data in FRELLED

Proof-of-concept 3D multi-wavelength data rendering in FRELLED. So far as I know, no other FITS viewer can do this.

The blue shows neutral atomic hydrogen clouds in the Milky Way while the red shows CO (a proxy for molecular hydrogen). The HI is from the GALFA-HI survey while the CO data is from the Extended Outer Galaxy Survey. A certain Kevin Douglas was kind enough to provide data sets which had already been correctly aligned.
