PsiOptParam(values_or_lower, upper, base_case)

PsiOptParam provides a list of different values that a variable should have in different optimizations.  Pass the lower limit for the parameter or alternatively, a list of values or a cell range, for the Values_or_lower argument and the upper limit for the parameter for the optional Upper argument. Pass a value to the base_case argument to be displayed in the cell when not running multiple optimizations.
