Lets remove this additional module and just put any helper functions directly the existing mod.

[0xKitsune]

Instead of adding this function, lets just mark the existing function in src/state_space/mod.rs as pub.

Same thing here lets dedup this function and expose whatever is necessary in the state space module.
