Using the Get_Elements_Dataframe function fails when there is an attribute with same name as the dimension. There is a uniqueness error produced.

ValueError: The column label 'Dimension Name' is not unique.

Because the attribute data is joined back to the element data there has to be a unique key/column (IE the dimension name column that holds the element names)

To Reproduce
Create a dimension called MyDim and then create an attribute for elements in that dimension called MyDim.

Expected behavior
I have modified the code to add a suffix to any attributes that have the same name as the dimension which solves the issue. Not sure if this is the best way to go about this or not.
