split netcdf4time into standalone package #601
Description
I'd like to propose splitting netcdf4time into a standalone package. The motivation for this request is coming from ongoing xarray development (pydata/xarray#1084) where we would like to use netcdftime without the complete netCDF dependency. This would not require any change to user code as netcdf-python would still be able to provide users the netcdftime module. I'd be happy to perform this task, including setting up TravisCI, Pypi, etc...
