FunctionXform can be applied several times

In the regular package, having applying several time FunctionXform would result in a failure:

Example:

dataBox = WrapData(data)

dataBox <- FunctionXform(dataBox,
                           origFieldName="x1",
                           newFieldName="x2",
                           formulaText="x1 + 1")

dataBox <- FunctionXform(dataBox,
                       origFieldName="x3",
                       newFieldName="x4",
                       formulaText="x3 * 2")                         

would throw an error. This version fixes the issue
