There are probably some stride-related gotchas involved in using
shallow_array_adaptors to wrap 1 and 2 dimensional MultiArray
implementations.  I believe MultiArray concepts/views can handle a
more general stride specification than uBlas matrix and vector types
may be able to.  In particular, the MultiArray 2D storage ordering
semantics are not encoded in types the way that uBlas has them.  Not
insurmountable, just something to be aware of.
