* Add a new PyTorch example to show embedding.
Update pybind document.

* Change the function of embedding to take word
dictionary.

* Use a more light weight method to get PCA and T-SNE. Update embedding documentations. Update loading animation

* Reveal the embedding tab

* Add the auto reload. and fix typos

* Update comments

* Fix the bug where the scalar chart is not showing time wall properly.

* Update Label to show wall time.

* Complete audio data integration:
* Add num channels, sample width, sample rate as params
* Generate audio file with proper params

* clang format

* Create Audio Feature in SDK
* Add apis to record audio in SDK
* Add corresponding apis in pybind, storage.py, sdk.h
* Implement reservoir sampling when collecting audio samples

* fix clang format and update based on comment

* use int_8 for reading records and convert string directly from vector

* refract isSampleTaken to IndexOfSampleTaken

* fix clang format again

* Add manual Save feature.

* Fix the incorrect style

* Add feature to record Text

* Create a simple UI for text preview.

* Connect frontend with backend text data

* Move a constant from parameter to the body.
Remove test log

* Add manual Save feature.

* Fix the incorrect style

* Add feature to record Text

* Fix the incorrect test cases

* Move the doc related commands to a script.

* Add X to the deploy_docs_on_travis.sh permission

* Add manual Save feature.

* Fix the incorrect style

* Adjust the sync_cycle automatically.

* Change the multiplier type to double.

* Adjust the sync_period.

* Fix comment.

* Add the pre-commit

* Run pre-commit with other files.

Let's reduce the complexity of the documentation for now. and maybe split the #define function in the future.

* Add the support to write documentation in the pybind directly.

* Provide more detail of the API documentations.

* Add Python 3 support

* Update protobuf to 3.5 and pybind to 2.2.2

* Update test scripts to use python -m

* Change zip/xrange/import usages

* Remove file generated by

* Graph viz set up (#282)

* Include the Graph requirement, GraphViz` in docs.

* Provide information to the ONNX format model export.

* Ask the user to download Graphviz via the website instead of brew.

* Make test and build scripts compatible with python 2 & 3

* A WITH_PYTHON3 option was added to cmake.

* setup.py will detect runing version python, and setup up WITH_PYTHON3 environemnt variable before calling build.sh

* build.sh and test.sh will handle WITH_PYTHON3

* Fix pybind warning

* Pass WITH_PYTHON3 correctly

* Fix coding style

* Add six for Python 2 and 3 Compatibility

* Fix coding style

* 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.

* Add C++ and python style check to travis.  
* Update all C++/python code that violate coding standards.

Fix some typos

* support manylinux build

* init comment for sdk

* update comment

* init paddle

* add image writer

* change sample numble to 4

* add image and conv image

* add histogram

* rename test file

* link in eigen3 library to vl_test target
* Add new "template class SimpleWriteSyncGuard<Entry<long long>>;", since build will fail on OSX
* Add template keyboard to data<T>(0).Get() (otherwise this fails on OSX)
* Fix unit test in sdk_test.cc

Tested build and unit test run on OSX and Ubuntu with no issues
