The current version of LogisticDx is 0.2 from 2015, and it doesn't 
export those functions.  Source for version 0.1 from 2014 is available, 
and it does contain those functions, but I wouldn't touch them with a 
ten foot pole unless I first heard from the author why he left them out 
of the next release.
