Pytorch weight normalization - works for all nn.Module (probably)
## Weight norm is now added to pytorch as a pre-hook, so use that instead :)

# Resample.py
# Andrew Brock, 2017
# This code resamples a 3d grid using catmull-rom spline interpolation, and is GPU accelerated.
# Resample along the trailing dimension
# Assumes a more-than-1D array? Or just directly assumes a 3D array? we'll find out
#
# TODO: Some things could be shared (such as the mgrid call, which can presumably be done once? hmm)
# between resample1d calls.
