*
* \brief A matrix or vector expression mapping an existing array of data.
*
* \param _PacketAccess controls whether vectorized aligned loads or stores are allowed (Aligned)
* or forced to unaligned (Unaligned). Defaults to Unaligned.
* \param MatrixType the equivalent matrix type of the mapped data
* \param _PacketAccess allows to enforce aligned loads and stores if set to ForceAligned.
* The default is AsRequested. This parameter is internaly used by Eigen
* in expressions such as \code Map<...>(...) += other; \endcode and most
* of the time this is the only way it is used.
*
* This class represents a matrix or vector expression mapping an existing array of data.
* It can be used to let Eigen interface without any overhead with non-Eigen data structures,
