Many Tools to help investigating issues

Developpers write many lines of code, many are part of a package, many are used to investigate what the first line produces. This section gathers some tools occasionally needed to write converters in sklearn-onnx, to implement kernels in onnxruntime, to add new operators in onnx. The first series is used to play with onnx files. A couple of the helpers described below are available through command lines.

The second series is used to investigate C++ implementations in onnxruntime.
