7c8722acad Print ASCII art "All Tests Passed" on success. 
It's nice to have a clear signal that I can read across the room
that everything was successful.  If I don't see this, I know
something went wrong.

0c824bcf1b Major performance improvement for C library: re-use Earth tilt calculations. 
Just like I did in the Python version, avoid repeated calculations
of the Earth's tilt angles for a given time. Do this by caching
the angles in the astro_time_t structure. This requires passing in
the time values by address instead of by value. I may go back and
change all the time parameters to pointers for consistency.

dfb888efb9 Measure time required by JS and C astro_check. 2019-06-27 15:27:01 -04:00

8615a2548a Huge performance boost to Python code: re-use e_tilt calculations. 
Calculate _e_tilt() no more than once per Time instance.
Cache the value in the Time instance and re-use it.
This reduced astro_check time from 5.0 minutes to 2.0 minutes.

f2478fa29d Improved performance in C and JS code by getting rid of ter2cel() function. 
I already did this in the Python code to significantly reduce the number
of calls to e_tilt(). Did the same thing here: call sidereal_time() once,
then use the value 3 times.

c611b50d3f Significant performance boost to Python code: eliminate _ter2cel(). 
There were 3 calls to _ter2cel(), each of which redundantly
called _sidereal_time, which results in 3 calculations of _e_tilt().
Reworked so there is only one call to _e_tilt().

Minor changes to support using cProfile, which is how I found this.

f85025da31 Implemented astro_check in Python. Exercises major parts of the code. 
There is still a slight discrepancy in calculations of altitude,azimuth
that is larger than between JS and C.

Don Cross
027a6af007 Adapted JS vsop code generator to work with Python code too. 
Now the Python code and the JavaScript code for VSOP models
are generated by codegen.c using the same $ASTRO_LIST_VSOP macro.
Python functions for calculating from VSOP are not yet implemented.

49e505e654 Verified GeoMoon C and Python versions are consistent for a single test case. 
This is a good indicator that the Python translation of CalcMoon is correct.

Don Cross
79df146194 More Python CalcMoon work in progress. 
Also made minor optimizations to spin() function in both JS and C.
Fixed a mistake in JS and C that does not appear to have any
algorithmic consequences, but it was definitely confusing once I saw it.
