// Code for StackOverflow Q&A: http://stackoverflow.com/a/32529850/2778484

// For example MATLAB-side implementation (class wrapper), see https://github.com/chappjc/MATLAB/tree/master/cppClass
// Use:
// 1. Enumerate the different actions (e.g. New, Delete, Insert, etc.) in the
// Actions enum. For each enumerated action, specify a string (e.g.
// "new", "delete", "insert", etc.) to be passed as the first argument to
// the MEX function in MATLAB.
