====== Select Transition Matrix ======

===== Description =====

Container that picks one transition matrix out of a series connected inside it, based on the current step. Each candidate matrix must be connected through a [[Number Transition Matrix]] hook, whose number identifies the step at which that matrix takes over. A matrix begins being selected once the model step reaches its number, and remains selected until the step reaches the number of another connected matrix, allowing one matrix to be swapped for another during a model's execution.

===== Inputs =====
