RoIAlign Operation for Theano

This is a fork of the RoIPooling implementation on Theano for the RoIAlign operation described in the paper "Mask R-CNN" by He et al.

Contributing

Currently only RoIAlign with max pooling aggregation has been implemented. However, rewritting it to average pooling is straightforward. Please be free to send a pull request if you have such.
