* @brief Contains mexplus template specialisations to convert eos data
* structures into Matlab.
*
* Note 1: These all copy the data, which I believe might be necessary, since
* Matlab may unload a mex module (with all its allocated data) at any given
* time.
* Note 2: They all return double vectors and matrices, even when the data given
* are floats. We can think about changing that if it's a speed issue, however,
* I think double is Matlab's default data type.
