AUTHOR Doug Scamahorn
DATE NAME DESCRIPTON
09/24/2007 Doug Scamahorn Initial creation.
12/10/2007 Doug Scamahorn Updated interactWithWidget function. When gathering form values the form was incorrectly targeted. Changed definiitio of variable "f" to f = bmiCalcForm;.
03/06/2010 Ben Rondot Added atlas tag and dcsMultiTrack to the submit function.
