% Code generator for the VA Matlab interface facade class
%
% Desc:     This script generates the code for the Matlab
%           facade class to the VAInterface MEXExtension.
%           It takes the class template code and inserts
%           all stubs for the functions in the VAConnector
%           interface. These are derived using the reflexion
%           mechanism ('enumerate_functions')
