#1812: Implemented logarithmic scaling for NumberLine / Axes
This implements scaling bases that can be passed to the scaling keyword argument of NumberLine. See LogBase (for a logarithmic scale) and LinearBase (for the default scale) for more details and examples.
#2152: Introduced API for scene sections via Scene.next_section()
Sections divide a scene into multiple parts, resulting in multiple output videos (when using the --save_sections flag). The cuts between two sections are defined by the user in the construct() method. Each section has an optional name and type, which can be used by a plugin (see an example). You can skip rendering specific sections with the skip_animations keyword argument.
