# PURPOSE : This file
# PURPOSE : This file contains a namespace called MatrixTable with its
#           functions. It's for managing matrix tables.
#           It's a child of BayesTable so inherites all its functionalities.

#
# PURPOSE: The purpose of this namespace is organize code and functions and
#          provides functions to create and manage a matrix object table.
#          A special namespace is created for each instance of Matrix table.
