* @brief Tuple to index conversion to provide column access.
*
* The following function provides conversion between a Python tuple and
* an integer array. This allows table column access via tuples, such as in
* a[(3,5,10)] = 10.0 or c = a[(2,9)]. Note that the typemap will be
* globally defined after inclusing of this file, hence GFitsTable.i has
* to be included before all table class swig files.
