first small edits
turning some functions to internal, and making sure that these functions return astropy Quantities.
made the true obliquity an astropy Angle Quantity
more edits to differential rotation
implementing astropy units in the rotation code
first working rot_hpc using existing wcs transformation code
improving the documentation
creating a mapcube solar derotation function
added in a function to test if the input is an astropy pixel Quantity, as this function is explicitly used in many different functions.
small change
small changes
replaced pixel testing function and added arcsec testing function
add in the rotation function
pulled out the solar differential rotation function
expanding tests
adding in notes
re-wrote the creation of the new, shifted mapcube.  Tests for applying shifts
fixed first working mapcube solar derotate
fix to apply shifts to get the right data clipped; still need to fix positioning information
removed prints used in debugging
