Parent: Aligns new point helpers to the parent objects pivot for the selected object.

Tip:
Use mGroup.help() in the listener for a break down of some of the functions that might be useful to call from other scripts, there are many others that make up mGroup.ms but are not useful by them selves for the most part.

Installation:
There are two scripts that ship with this tool. mGroupMacros.mcr is the macro scripts and should be placed in 3DSMax/UI/Macroscripts folder. mGroup.ms is the struct that contains all the functions to run “M” Group and should be placed in 3DSMax/Scripts/Startup. Restart Max and add the Macros to your favorite hot key or quad menu. They are found under the “M” Group category.
