 Type of gene is enum that provides different functions. Here is (Very WIP) list of every type and its provided functions:
 
-Dummy - gene without behaviour.
+Structural - gene without behaviour.
 
 Transport - gene that defines rules of flow.
 - `distribute_between_children(<context>) -> ChildDistribution`
