This allows arbitrary partitions to be used in the calculation.

This returns the effective number of groups, taking into consideration
their sizes.

This adds the "dynamics" submodule, with implementation of several
dynamical processes.

This improves performance of the Python API.

Nodes with out-degree zero are now assumed to connect to every other
node.

This enables linear-time computation of shortest distances on DAGs that
also allows for negative weights.

This re-enables the 'register' keyword with C++17, which is still
required for Python 2.

Use gammaln() in place of log(gamma()).
