* @class vtkSplitColumnComponents
* @brief split multicomponent table columns
*
*
* Splits any columns in a table that have more than one component into
* individual columns. Single component columns are passed through without
* any data duplication.
* NamingMode can be used to control how columns with multiple components are
* labelled in the output, e.g., if column names "Points" had three components
* this column would be split into "Points (0)", "Points (1)", and Points (2)"
* when NamingMode is NUMBERS_WITH_PARENS, into Points_0, Points_1, and Points_2
* when NamingMode is NUMBERS_WITH_UNDERSCORES, into "Points (X)", "Points (Y)",
* and "Points (Z)" when NamingMode is NAMES_WITH_PARENS, and into Points_X,
* Points_Y, and Points_Z when NamingMode is NAMES_WITH_UNDERSCORES.
