Feature request: Translate matrix position when switch matrices

[JackMostow]

Is your feature request related to a problem? Please describe.
A clear and concise description of what the problem is.
When RoboTutor switches matrices, translate position in current matrix to corresponding position in new matrix.

Describe the solution you'd like
A clear and concise description of what you want to happen.
If current activity also exists in new matrix, stay at that activity, i.e. use activity name to represent position in matrix.
If current activity does not exist in new matrix, find "nearest" activity that does.
Fortunately, this condition occurs only in going from unfiltered matrix to filtered matrix.
Compute the "nearest" relation off-line using the .csv form of the activity matrix, before it gets expanded into .json used at runtime.
@pravallika10473 [ ] Generate the translation table for each content area.
@ssvaditya [ ] load it at start of session to use at runtime.

Code Drop Filtered Matrices

@pravallika10473 [ ] For each cell in (unfiltered) [Copy of Literacy3] =counta($1:$18)=1309

(https://docs.google.com/spreadsheets/d/1Qk1Phfnai4TqRhE0R1Kku6Ew7A8bYPiFgakYUlbEi-8/edit#gid=34600496)
Map it to next cell that appears in (filtered) Copy of Literacy3_squeezed.csv
thereby skipping the activities filtered out as unworthy-ish

Represent the mapping so it's easy to load and apply at runtime.

[ ] For additional context, other MAB meeting notes might be useful.

[ ] Need to find script(s) (in GitHub?) for expanding .csv matrix into .json format.

Translation table has been generated but needs to be loaded and used.
