This release is a prerelease of version 3.0 with finished simulator handling for
the NEST simulator and preliminary support for TreeCollections, tree pickling,
MorphologyRepositories, morphologies, voxelization and touch detection.
* Added MorphologyRepositories to preprocess and store morphologies before they
are used in the placement/connectivity.
* Added TreeCollections to load, cache and store trees. OutputFormatters should
know how to handle trees.
* HDF5Formatter can pickle trees.
* Simulations can be configured through SimulatorAdapters, should provide
ConfigurableClasses to configure `cell_models`, `connection_models` and
`devices`.
* Implemented a NestAdapter with NestCells, NestConnections and NestDevices.
