Function Details

setupModels()

Attempts to do the initial load of all models. Must be called on script startup.

This method scans the the model directory and finds all python scripts available. It computes a hash of the scripts (i.e. a 'version') then attempts to load all NPSGD models held within, using the version previously configured.
