bdc84e6d15 Python: _iau2000 is a little faster. 
riseset test now runs in 20.3 seconds.
Converted all _iaudata to explicit float, and use tuples instead of lists.
Both appear to help.

0ac3fa708f fixaddsol: Major performance improvement: 29.1 seconds. 
Use dictionaries instead of creating custom array classes.
That way co[] and si[] subscripts are much faster.

810724a7da Python: Another _CalcMoon performance improvement. 
Reworked Term() to use less array indexing; pack and unpack tuples instead.
Execution time for riseset is just below 51 seconds now.

adc424106c Python: Improved performance of _CalcMoon. 
I unrolled the loop in the Term function.
The riseset test now runs in 52 seconds instead of 56.

9359b80c42 Fixed #46 - Python calculations exactly match C calculations. 
The problem was that the Python "%" operator does not behave
exactly like the C function fmod().  However, there is a Python
function math.fmod() that does act just like its counterpart in C.
Now astro_check output is *identical* between Python and C,
at least on my Windows 10 laptop.

Reinstated "ctest diff" in unit tests to make sure the
two implementations stay in sync.

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.

Don Cross
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.

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.

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.
