Documentation is out of date

[nmerket]

Describe the bug

The documentation at https://eemeter.openee.io/index.html doesn't reflect the latest version of the package, 4.0.

For example, trying to access functions in modules in the tutorial and the API aren't available

import eemeter
eemeter.create_caltrack_billing_design_matrix

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'eemeter' has no attribute 'create_caltrack_billing_design_matrix'

Expected behavior

The documentation should reflect the current state of the software.

Additional context

None

This is something that either needs to resolved.

In the meantime if you are trying to use OEEM 4.0, please refer to the tutorial in the repo.
