+List of configurable setting in the simulation:
+    - Number of body types
+    - Body type colors
+    - Interactions between body types
+    - Friction value
+    - Near repulsive force
+    - Universe scale (used in relation to forces)
+    - Number of threads

+Config file will look like:
+
+body_type_count 4
+body_color 0   1.0 0.0 0.0 1.0
+...
+interaction <t1> <t2> <d> <f>
+interaction 1 2 100.0 20.0
