Python module install of CASA 6

Pip wheels for casatools and casatasks are available as Python 3
modules from the public PyPI server casa-pip.nrao.edu. This allows
simple installation and import in to standard Python 3.6
environments. The casatools wheel is necessarily a binary wheel so
there may be some compatibility issues for some time as we work toward
making wheels available for important Python
configurations. Initially, we are targeting Python 3.6 as provided by
RedHat for our wheel production, with RH6 and RH7 as official
supported platforms. We have had some success on other Linux-based
platforms as well, but we do not recommend the use of Conda until
compatibility with Conda is better understood.

The following prerequisites must be present on the host machine before
installing CASA:

Python 3.6
libgfortran3 (yum or apt-get install)

Installation instructions are as follows (from a Linux terminal
window):

$ python3.6 -m venv casa6

$ source casa6/bin/activate

(casa6) $ pip install --index-url https://casa-pip.nrao.edu/repository/pypi-casa-release/simple casatools

(casa6) $ pip install --index-url https://casa-pip.nrao.edu/repository/pypi-casa-release/simple casatasks


Test with the following:

 which python
~/casa6/bin/python


(casa6) $ python

Python 3.6.9 (default, Nov 7 2019, 10:44:02)
