A data model for describing demographic models.

The demes specification defines a data model for describing one or more demes (or populations), how they change over time, and their relationships to one another. A human-readable demes model is written as a YAML file, which facilitates model sharing, reuse, and interoperability. A reference implementation for loading demes models into python is available from https://github.com/popsim-consortium/demes-python
