[x3d-public] string sequencer/interpolator ?

[Andreas Plesch]

While working on the IntegerSequencer test

https://glitch.com/edit/#!/x3dom-sequencer-interval-test?path=IntegerKeyTest.html:54:10

it was necessary to use a lot of switch nodes to display different texts
depending on some input.

With a StringSequencer one could directly feed text into Text nodes,
selected by a key. This would substantially streamline scenes with dynamic
or conditional text. Maybe String/TextSequencers/Interpolators had been
discussed at some point ?

Since such a StringSequencer would need to have multiple MFStrings as
keyValues, a practical issue would become how to encode such an array of
MFStrings in xml (and json). A MMFString in effect.

Add another layer of quotes ?
keyValue=" ' "MFString1_a" "MFString1_b" '  ' "MFString2_a" "MFString2_b" '
"

Use comma as a dedicated delimiter ?
keyValue=' "MFString1_a" "MFString1_b", "MFString2_a" "MFString2_b" '

Some other delimiter (vertical bar |) ?
