[x3d-public] FloatSequencer ?

[Andreas Plesch]

Here is the

http://x3dgraphics.com/examples/X3dForWebAuthors/Chapter09-EventUtilitiesScripting/ScriptComplexStateEventsIndex.html

converted using a ScalarSequencer (naming following ScalarInterpolator):

https://quirky-winter.glitch.me/

And here are the relevant changes to the scene

https://glitch.com/edit/#!/quirky-winter?path=index.html:75:7

Replacing the script and its custom field declarations, there is now only
one Sequencer node, one ColorInterpolator and one additional route, three
lines.

This pattern would be the main intended usage, eg. using sequencer fraction
output to get interpolator typed output for use in the scene (colors,
orientations, positions ..).

How does that look ?
