Rhythm 1.0 - musical BPM and time signatures for Blender

This add-on adds a new panel to the “Render” property tab, allowing to set a tempo (bpm) and time signature for a scene, which starts counting from the first frame of the animation range.

The header of the timeline view will display the measure of the current frame as bars, beats and fractions. Each frame that is closest to the next full beat is marked with a star (*), which may also serve as a visual metronome during playback.

The panel also shows the resulting beat and bar rate in Hz, to serve as guide for configuring cyclic animation drivers.
