Re: [eigen] New(?) way to make using SIMD easier

PICNIC: Problem in Chair, Not In Computer.

When I looked back over the code I realized that I had not replaced 
*all* of the "VectorXf::Map"s with "MapAligned".

Once I did that, the MapAligned code and vector_add ran the same speed.

Thanks for your patience,
