====== Categorical Map Junction ======

===== Description =====

This functor chooses one of two possible categorical maps produced from different execution pipelines.

===== Inputs =====

^ Name            ^ Type                                      ^ Description                                                     ^
| Possible Map 1 | [[Categorical Map Type | Categorical Map]] | Map of classes or categories output from an execution pipeline. |
| Possible Map 2 | [[Categorical Map Type | Categorical Map]] | Map of classes or categories output from an execution pipeline. |

===== Notes =====

First, this functor verifies whether there is a valid input in "Possible Map 1"; if not, it chooses "Possible Map 2" as input. It is a convenient way to provide an alternate categorical map in case an execution pipeline does not return a valid data. If "Possible Map 2" is not set, the functor will return a void output.
