Column Headings as Array Variable

Stores list of column headers as an array variable. This can then be used later in a column filter to ensure that only those columns that were originally in the table will be kept after any other processing has occurred.

Column selection array variables can be used with a variety of needs for ensuring the required columns are selected or deselected
