~~~ Design Notes ~~~

This is part of a series of LIST functions.
ListAdd, ListAddUnique, ListExist, ListGet, ListToggle.
Each uses the same name format: List
Each uses the same parameter format: InList; InValue.

They also work in concert with two SET functions:
SetVar and SetField
These are all designed to work with variables and to
keep the variables from being un-set (removed from memory),
by using the string "Empty" to indicate IsEmpty().
Example:
If a field, MyField, is empty and I use SetVar(),
MyVariable = SetVar( MyField )
Tnen MyVariable is now = "Empty"
