Quagmire v0.5.0 Beta

Release Notes v0.5.0b

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
• Introducing MeshVariables which wrap PETSc data vectors and provide interoperability with quagmire 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 interface
