harmonized unit test with torch7/cutorch/nn
Fixed padding and scale parameter.
fixed default tensor in test bug
Merge branch 'master' of github.com:torch/cunn into mixturetable
Merge pull request #20 from nicholas-leonard/mixturetable

Harmonized test suite
Removed half-baked (and old) module SpatialConvolutionMap
SpatialConvolutionMM:updateOutput() supports 3dim
SpatialConvolutionMM supports dim=3 (once gradBias is implementeD).
added DistKLDivCriterion CUDA implementation and a unit test for it.  Also added modified the MSE unit test to include sizeAverage tests as well (to get all code paths).
removed redundant kernels from DistKLDivCriterion and modified test.
added a CUDA version of Min (basically copy-paste from Max).
Merge pull request #24 from jonathantompson/min

added a CUDA version of Min (basically copy-paste from Max).
Merge pull request #23 from jonathantompson/kl_divergence

added DistKLDivCriterion CUDA implementation and a unit test for it.
SpatialConvolutionMM now supports arbitrary batch sizes (and 3-dim
        inputs)
Deprecated SpatialConvolution.
Incorporated rectangular filter support recently added in Caffe repository.
