Description
This PR fixes a memory leak that was occurring in the Python-side
qcdb
code. The code meant to modify a class variable but was actually creating and modifying an instance variable. Initialization happened many more times than needed, and some memory was not being cleared upon object deletion.The only explanation I have for how this produced a memory leak is that having a class variable and an instance variable with the same name confused the Python garbage collector. I was able to confirm object creation and deletion was occurring roughly as expected.
