v0.93

============================== Release Notes: v0.93 ==============================

This release contains a major refactoring / overhaul of the code base.
Key highlights include:

• Moving layer design into smaller simpler layers that have a single
  compute behavior per layer. Specifically, linear combination of the
  inputs, non-linear activations, and regularizers now exist as their
  own layers.
• Layers now have a template parameter that specifies the data layout
  for the distributed matrices.
• Prototext interface for specifying neural network models and data
  readers is nearly fully functional.
• Code now adheres to internal coding style as outlined in
  README_coding_style.txt
• Dead-code has been eliminated and layer file hierachy has been
  cleaned up.
