Title: Locally connected layer

This PR implements a locally connected layer, as described in [1], for example.

It's similar to convolution, but there is no weight sharing.

Ye Lu and I worked on this together. Working code is mostly his. Bugs are mine.

We wrote this a while back, before the convolution layer supported non-square filters and strides. I can add support for that if there is interest.

Looking forward to hearing your comments.
