rArgument: The argument which is changed to a Boolean value, if possible. Function returns False if conversion was not possible, such as when the argument is out-of-range, missing, Null, an error, a pointer, or a non-numeric string.
Note: rArgument is a passed by reference, so the variable passed from the calling function will likely be modified.

Example #1: 

    Assuming
       Dim varFlag As Variant
       varFlag = "0"
    for example
       FixUpVariantToBooleanMandFn(varFlag) = True
    leaves
       varFlag = False
       VarType(varFlag) = vbBoolean
Example #2: 
    Assuming
       Dim varFlag2 As Variant
       varFlag2 = "Word"
    for example
       FixUpVariantToBooleanMandFn(varFlag2) = False
