add lookAtSpheroid

Add lookAtSpheroid to Python, Matlab/Octave, Fortran code. This determines the intersection point of a look angle from an object above the spheroid

improve test modularity and robustness with minimum prereqs (Numpy)

console entry points

• CI Template update
• console scripts easier to use

Modernize setup and test

modernize setup (setup.cfg)

Cleanup Fortran

• Cleaned up Fortran code error handling
• fixed Python code coverage testing
• Readme.rst => Readme.md

Type checking, flake8

Use flake8 and mypy type checking to improve correctness

• Python >= 3.6 required

Improve robustness for CMake Fortran build & Matlab self-test

v1.6.4

Merge branch 'master' of ssh://github.com/scivision/pymap3d

allow radians or degrees into angular separation

This speeds up massively repeated operations of these functions--convert once to radians beforehand instead of each time (optionally)

cleanup, test coverage, argument expansion

Lots of little improvements:

• cleaned up Python self-test and improved coverage via argument expansion
• added AppVeyor (windows testing)
• published in
• using Ctest

Fortran radians bugfix, add err_msg to Fortran & Matlab assert

• Fixed incorrect calculations with "radians" input angles to Fortran code.
• allowed "err_mag" text message for assert_isclose() in Fortran and Matlab code, like Python
• improved test coverage in Fortran and Python.

Correct function/variable names

Corrected names of anglesep (angular separation) formulas.

Added radec2azel,azel2radec to Fortran.

Updated paper to describe Fortran code
