Non descriptive variable names

[TheLukaszNs]

In some places of the code, we are using the variable names that are nor self-descriptive, nor really documented. Example:

# main.py

g = Graph()
g.load_graph(...)

In the above piece of code the developer can come up with an idea on what the g stands for, but if the code will become bigger and structured like this, we won't be able to identify which this variable stands for. 😕 We should either use more self-descriptive names, like:

graph = Graph()
graph.load_graph(...)

or document those variables.

This problem exists in all of the project files, we should really think about fixing it.
