Bug Fixes and Improvements:

+ Fix Caffe constant emit
+ Add visual studio solution file
+ Add pytorch_emit [Prelu]

+ Add keras_parser [Conv1DTranspose], [Conv2DTranspose], [Conv3DTranspose]

1. Initial implementation for RNN operators including GRU (Gated Recurrent Unit) cell, LSTM (Long Short-Term Memory) cell (no support for peephole yet) by matching the cell's corresponding pattern and fold them into a fuction or class in target framework.

2. Various fixes and stability improvements.



1. Support for for ssd and fastrcnn in tensorflow frozen parser.

2. Initial support for resnet-v2 , inception_resnet-v2 and facenet.

3. Add some ops which include Pack, Shape, Scale, StrideSlice, Prelu, Mul, Abs, Sub, Squeeze.



Formal release of CoreML parser and Caffe/Onnx/CoreML emitter. darknet parser initial release.
