hpgeom 1.3.2

HPGeom
A lightweight implementation of HEALPix geometry functions, wrapped in a numpy interface.
The implementation is based on the geometric functions in the original HEALPix C++ library code.
This package has an all-new API, and also includes compatibility functions with the same interface as healpy for an easy transition from healpy to HPGeom.
Requirements:
At runtime, HPGeom requires numpy.
At build time, a working C compiler is also required.
The full suite of tests require healpy.
Install:
The easiest way to install HPGeom is from pypi (pip install hpgeom) or from conda-forge (conda install hpgeom -c conda-forge).
To install the package from source go to the parent directory of the package and run pip install ..
To include all test requirements, install optional dependencies with pip install .[test,test_with_healpy].
