+### Nested Classes
+A problem I noticed after using this library is that some of the function call names weren't very intuitive/easy to
+remember. But short of having a better way to "group" related functions, I wasn't sure how to improve upon this.
+
+After implementing nested classes in my "Linear Programming" solver project, I realized this issue may be addressed with
+nested classes. The logic for using nested classes is fairly close to the original logic, while allowing all node and
+edge functions to be grouped together in a (hopefully) more intuitive manner.
+
+Inspiration came from how Django handles "model query managers" with the "models.objects.<query>" syntax.

 some trial and error, the general idea worked.
 
-### Circular Dependency Fix
-The Node and Edge classes each import each other, so that they can check that they are being passed values of type
-Node/Edge. Unfortunately, this appears to cause a circular dependency, which causes errors when using the standard
-`from x import y` syntax.
