/*! \brief Create memory data source from mxArray

\code
system={
	type="mexDS";
	varname="";            // name of workspace variable
	rids=[1 1 1];          // numbers of data rows
	tds =[0 1 2];          // time delays
	};
\endcode

MemDS with the above fields will be created;

\todo Very memory inefficient implementation. The data file is copied 2 times! 
For better implementatin we would need MemDS with pointer to the raw data. Then it could operate directly inside mxArray.
