_API docs for this extension are included in the DataTable class._
Class extension to add mutation convenience methods to `Y.DataTable` (or other

Column mutation methods are paired with new custom events:
* addColumn

Row mutation events are bubbled from the DataTable's `data` ModelList through

Adds the column configuration to the DataTable's `columns` configuration.
If the `index` parameter is supplied, it is injected at that index. If the
table has nested headers, inject a subcolumn by passing an array of indexes
to identify the new column's final location.
The `index` parameter is required if adding a nested column.
This method is a convienience method for fetching the DataTable's `columns`
attribute, updating it, and calling
`table.set('columns', _updatedColumnsDefs_)`
For example:
<pre><code>// Becomes last column
table.addColumn('name');
// Inserted after the current second column, moving the current third column
// to index 4
table.addColumn({ key: 'price', formatter: currencyFormatter }, 2 );
// Insert a new column in a set of headers three rows deep. The index array
// translates to
// [ 2, -- in the third column's children
// 1, -- in the second child's children
// 3 ] -- as the fourth child column
table.addColumn({ key: 'age', sortable: true }, [ 2, 1, 3 ]);
