/**
* DataTables settings object - this holds all the information needed for a
* given table, including configuration, data and current application of the
* table options. DataTables does not have a single instance for each DataTable
* with the settings attached to that instance, but rather instances of the
* DataTable "class" are created on-the-fly as needed (typically by a
* $().dataTable() call) and the settings object is then applied to that
* instance.
*
* Note that this object is related to {@link DataTable.defaults} but this
* one is the internal data store for DataTables's cache of columns. It should
* NOT be manipulated outside of DataTables. Any configuration should be done
* through the initialisation options.
* @namespace
* @todo Really should attach the settings object to individual instances so we
* don't need to create new instances on each $().dataTable() call (if the
* table already exists). It would also save passing oSettings around and
* into every single function. However, this is a very significant
* architecture change for DataTables and will almost certainly break
* backwards compatibility with older installations. This is something that
* will be done in 2.0.
