Add option to collect mand variety data
Therapists can enter different mands throughout the session (e.g., go play, eat popcorn, throw ball, etc.). However, if at any point during the session the mand is prompted, therapists have the option to remove it or mark that it was prompted so it does not calculate into session variety of independent mands. At the end of the session, independent mands are calculated (e.g., 10 different mands). Right now there is a frequency option, but there is not a way to tell if different mands are being used or if it is the same mands over and over again.
