have a list of custom attrs, in case these attrs live under one node that I call brain which controls the state
of the rig. This is the place an animator goes to , to setup the rig the way he/she needs for the particular shot
he/she is working on. This includes ik/fk arms, spine, visibility switches, fingers etc , you name. I wanted to
have a quick way to reset the control rig into its default pose. A quick way for the animator to return back
to the original setup,as supposed to going through all the attrs and setting those up one by one.
This can be used for facial expressions or any number of attributes that need to be set certain way.
We can also include a function that would write these values out , and load function that would load the values.
