This issue is to increment version in documentation and installation files in preparation for release.

Before merge :

• Merge Issue80 pipe references #216

• Review pygfunction documentation

After merge :

• Create release tag
• Upload pdf documentation
• Update default version page on readthedocs
• Upload to Pypi

In #139, we proposed to follow the Anaconda distribution for package versions.

This necessitates the following changes in the requirements:

• numpy: 1.20.1 -> 1.21.5
• scipy: 1.6.2 -> 1.7.3
• sphinx: 4.0.1 -> 4.4.0
• numpydoc: 1.1 -> 1.2
• matplotlib: 3.3.4 -> 3.5.1
• pytest: 6.2.3 -> 7.1.1
• pytest-cov: 3.0.0 (no change)

Latest version of dependencies not in the anaconda distribution are the following:

• CoolProp: 6.4.1 (no change)
• tox: 3.24.5 -> 3.25.1
• recommonmark: 0.6.0 -> 0.7.1

Unless the last two are needed to support the other changes, I don't see a reason to update the versions.

The build is uploaded to testpypi : https://test.pypi.org/project/pygfunction/2.2.0rc0/

Install using pip install -i https://test.pypi.org/simple/ pygfunction==2.2.0rc0

The documentation builds without warnings with sphinx 4.4.0 and numpydoc 1.2.0 after 03a142a.
