-"""
-    fhn(du, u, p:FHNParams, t:)
-
-    Implements the spatial dynamics of FitzHugh-Nagumo (fhn). Designed to be 
-    within a larger numerical solver of partial differential equations.
-
-    # Arguments
-    - `du`: output argument which stores the calculated derivatives 
-    - `u`: input vector containing the current state of the system at time t
-    - `p`: holds all the fixed parameters of the FHN model
-    - `t`: current time 
-
-    # Returns
-    - `du`: calculated derivatives put back into the du array
