This is a revival of the mod CrewQueue, which was orignially written by @enneract in 2015. Original thread is here: http://forum.kerbalspaceprogram.com/index.php?/topic/97702-10x-crewqueue-crew-rotation-and-vacations/
The mod had been updated by @Starwaster for 1.1.3, which is where I cloned the source code from.
