Error building documentation. "AttributeError: module 'pyspod' has no attribute '__copyright__'"

[jdmoorman]

Running the following as explained in README.md results in an error.

$ git clone https://github.com/mengaldo/PySPOD
$ cd PySPOD
$ python setup.py install
$ cd docs
$ make html

The resulting error message output by make html follows.

Running Sphinx v2.4.2

Configuration error:
There is a programmable error in your configuration file:

Traceback (most recent call last):

    copyright = pyspod.__copyright__
AttributeError: module 'pyspod' has no attribute '__copyright__'

make: *** [html] Error 2

Looks like the issue is related to the variables (e.g. copyright) defined on lines 22-29 of docs/conf.py being overwritten on lines 72-75 and 85-87 by undefined metadata from the pyspod package (e.g. pyspod.__copyright__).
