* ADD: basic use of binary messages for faster coordinate data transfer
* ADD: updated to newer `NGL` version, (e.g. orthographic camera, anti-aliasing, much faster rendering, ...)
* ADD: `view.delay` property to adjust trajectory playback
* ADD: `show_url` function for loading & viewing from an url
* ADD: `view.hide()` and `view.show_only()` convenience methods
* ADD: `show_rdkit` function to view rdkit Mol objects
* ADD: `view.clear()` for clearing all representations
* ADD: `view.add_unitcell()`, support for the new NGL unitcell representation
* ADD: automatic creation of attributes: `view.trajectory_0`, `view.trajectory_1`, `view.component_0`, ...
* ADD: specify `component` index in `view.add_representations`, `view.clear_representations`
* ADD: drag and drop files into widget
* ADD: extra TrajectoryPlayer widget available via `view.player`
* ADD: `view.camera` property (`perspective` and `orthographic`, new in NGL)
* ADD: `view.background` property to change the viewer background (color name or hex value)
* ADD: `view.orientation` property to synchronize cameras of two viewer widgets
* ADD: view multiple trajectories via `view.add_trajectory()`, `view.add_component()`
* ADD: `view.download_image()` to render high quality image and trigger download in browser
* ADD: `view.render_image()` to render image for display in the notebook
* ADD: `view.center_view()` to center
* ADD: select atoms by their indices, given as a List
* ADD: shortcuts for view.add_representation (view.add_cartoon, view.add_rope, ...)
* ADD: `ParmEdTrajectory` adaptor and `show_parmed` function to view ParmEd objects
* ENH: `view.add_trajectory` now accept `pytraj.Trajectory`, `mdtraj.Trajectory`, `MDAnalysis.Universe`, `parmed.Structure`
* ENH: view.add_representations now accepts keywords in both snake_case and CamelCase
* ENH: smoother trajectory playing
* ENH: smoother rendering when adding new representation
* MIGRATION: change html/static to js/
* MIGRATION: change sending base64 to binary coordinates
* MIGRATION: change `view.trajectory` to `view.trajlist`
* MIGRATION: change `get_frame_count` method to `n_frames` property
* MIGRATION: remove `get_coordinates_dict`
* FIX: symlink error
