Nglui

- **StateBuilder** You can now set split points using a SplitPointMapper

Added

- **Parser**: `get_selected_ids` does what it says for a layer.

Fixed

- **Parser**: Getting annotations with tags/descriptions/etc works.
- **StateBuilder**: `return_as` parameter works with ChainedStateBuilder now

Fixed

- Remove pytables from requirements, because the pip install does not work on OS X (at least). If you want to run tests, you will need to install either with `pip install tables` if you're on a system where that works or `conda install pytables` otherwise.

Added

- **StateBuilder**: At long last, a BoundingBoxMapper
- **StateBuilder**: A `from_client` function to generate simple image & segmentation states from a FrameworkClient instance.
- **StateBuilder**: Statebuilder can take a client to configure certain default parameters.
- **StateBuilder**: SegmentationLayerConfig explicitly takes some view keyword arguments: `alpha_selected`, `alpha_3d`, and `alpha_unselected`.
- **Parser**: New options to get annotation groups and group ids for all annotations.
- **Parser**: New function to extract multicut information from a state.

Fixed

- **StateBuilder**: Fixed a scenario where int64s get altered by a conversion through floats.

Changed

- **Statebuilder**: Behind the scenes refactoring that should not affect use.

Fixed

- **StateBuilder**: Setting view options for Graphene segmentation layers now works
- **Parser**: Now imported as a property of nglui if you import as `import nglui`.
- Small bug fixes.

Added

- Parser submodule `nglui.parser` for quickly extracting data from neuroglancer states.
This should remove some of the boilerplate one writes every time you want to get data out of a state.

- AnnotationLayerConfig now can take arguments about user interactions such as filtering by segmentation and bracket shortcuts showing segmentations.

Changed

- Default behavior for annotation layers now has filtering by segmentation turned off and bracket shortcuts showing segmentations turned on.
