Godot Dependency Graph creator

This is a tool to create a dependency graph in order to show proper separation of your code and also the complexity of it.

TODOs

• check how to provide a simple way to scan all the files for their dependencies
  • scan .tscn files for [gd_scene...] and [ext_resource...]
  • scan .gd files for "signal" and "connect()" and "var" + "get_node" (or equivalents like "$someNode") and "var" + "preload"
  • how to check for things like "GameVariables" which is a global autoload?! -> can be read from .godot file!
  • do we also need to check for "class_name" in .gd files?!
• which visualization program / format should we use to express our graphs?
