tests pass on today's dev
remove vestigal bits of conv layer
example .prototxt files with local layers
prototxt files showing a siamese network with two local layers
i also added another contrastive loss after the first local layer, because
it seems to plateau otherwise
fix Reshape() to take on the appropriate tasks
cleanup: rename "local weighted conv" to just "local"
cleanup: merge gradient kernels into layer's .cu file, remove debugging cpu impl
finish renaming
merge import layer into local branch
Merge branch 'local_import' of github.com:jackculpepper/caffe into siamesehinge
