This is the first formal "public" release of the code.
High level summary of changes
Introducing quagmire.function which is a collection of lazy-evaluation objects similar to underworld functions

Providing context manager support for changes to topography that automatically update matrices appropriately
Making all mesh variable data arrays view only except for assignment from a suitably sized numpy array (this is to ensure correct synchronisation of information in parallel).
various @property definitions to handle cases where changes require rebuilding of data structures
making many mesh methods private and exposing them via functions
upstream integration is a function on the mesh
upstream / downstream smoothing is via a mesh function
rbf smoothing builds a manager that provides a function interfac
