Scipy trait types
Custom trait types for scientific computing (NumPy, SciPy and friends).
The goal of this library is to provide a reference implementation of trait types for common data structuresused in the scipy stack such as numpy arrays, pandas and xarray data structures which are out of the scope of the main traitlets project but are a common requirement to build applications with traitlets in combination with the scipy stack.
Another goal is to create adequate serialization and deserialization routines for these trait types to be used with the ipywidgets project (to_json and from_json). These could also return a list of binary buffers as allowed by the current messaging protocol.
