RHT added optional BAD data types. Planck data!
Writing Hthets to Disk incrementally during rht()

CODE WILL NOT RUN YET.

I still have to define:
concat_along_axis_0(memmap_list) @Line 441

and also test the thing before we use it.
If you really need to use this commit, set BUFFER = False @Line 35
Buffering MAY work now. NO GUARANTEE.
Buffering support added. New theta_rht() function.
Ok, Buffering is working! But not deletion.
New Plotting of ThetaRHT! Weird for theta=0, 90!
New plotting function works. All is well.

Need to discuss file output options..
Big changes, but not big enough.
Single Staircase!
Code Cleanup
Run, Run, as fast as you can!
More to do...
Lots, but still not ready yet
Cleaning up before next big push.
So close!
Big changes!

Output is now .fits formatted.
Output contains backprojection, parameters, and i, j, theta arrays.
Fast_hough is a faster thanks to einsum.

Functions interpret() and viewer() are Non-Functional right now, so
avoid -d.
Merge pull request #10 from Schudel888/master

New Plotting tools display thetaRHT. Next up is file output.
