* Add preliminary support for Windows

    Known issues:

    1. No zlib support for protobuf
    2. Manual editting to core.vcxproj are required
    3. No build and packge script support
    4. Not tesetd, may break linux build

* Add build script and batch file for Windows

* Fix linux build and include batch file in wheel

* Fix Python 2.7 build

* Define NOMINMAX instead of preventing macro expansion

* Binary Record Fixes

* Fixed issues with binary_record.h filename generator method.  std::hash is not consistent across OS.  It will generate different hash's when ran on different OS on the same string.  Change the filename generator to use a static counter.  It will be more ideal to use UUID generator available in boost 1.4.2, however, boost 1.4.2 has problems compiling on c++11 \n* Fix issue with pytorch demo where it logs to the absolute path /workspace

* Fix performance issue on server when server fails to load image file.  Currently server retries an API call 3 times before it fails, at which point it'll sleep the thread for 2 secs.  This becomes problematic when there are alot of SDK errors.  I'll create seperate issue to refine the retry logic to not be so expensive on the server.

* support manylinux build

* add third_party and refactoring cmake

* support pybind

* fix build error

* add storage_proto as dependency

* update gflags
