[x3d-public] Turning on and off simultaneous animations individually

[Holger Seelig]

With animations, it is actually usual to only have as many TimeSensor nodes as there are animations and then switch them on and off one after the other by toggling the *enabled* field, or via *startTime* and *stopTime*. The *fraction_changed* field of each TimeSensor node can also be connected to several interpolators, which is more optimal.

Currently, our animations go from key = 0 to key = 1, (weight = 0 to weight = 1) and each animation is controlled by a single TimeSensor that we enable or disable.  What we want to do is enable multiple facial animations, yet retain a single TimeSensor.  I have done something with enabling multiple time sensors all at the same time.  So, ideally, we could toggle each facial animation individually.
