6530c8f5b4 A much simplified version of the earlier commit introducing way fewer changes compared to changeset f292d2352e0ac9be8a9c5b0d931dc9a2c6da1aa0 
.
The reason of the previous commit was incorrect. The smart pointers issues were actually a result of issue 9.

71e5cbcbc4 Added specializations for DontAlign when using Dynamic matrices. 
This allows users to store Matrices in smart pointers without the
need for a specialized allocator/de-allocator.
