This PR:
-Fixes a major bug with generated javascript for using columns from different histograms/dataframes in one expression
-Fixes a bug with counting the length in joins on the client
-Adds a prototype implementation of #352

Template layout for tabs

We can make diff in respect to the varNorm - this is done per variable and we can compare different statistics with different weights

Combinations:

• normVar - [Yes,No], normWeight - [Yes,No]
• 3 value - 2D,3D, 4D

Old templated had only normVar - [Yes, No]

Test layout tabs

• histXY. - as before
• histXYWeight
  0,0 - mean, median weight
  0,1 - rms for weght
  0,2 -entries for wight
  1,0 - mean, median for reference wight
  1,1. - -entries for reference wight
  1,2 - -entries for reference wight
  2,0 - diff mean, median weight. (diff - minus or ratio)
  2,1 - diff rms for weight (diff - minus or ratio)
  2,2 -diff entries for wight (diff - minus or ratio)

#Layout to test histoXYZWeight
similar as above but with colorZ
histXYWeight
0,0 - mean weight
0,1 - rms for weght
0,2 -entries for wight
1,0 - mean, median for reference wight
1,1. - -entries for reference wight
1,2 - -entries for reference wight
2,0 - diff mean, median weight. (diff - minus or ratio)
2,1 - diff rms for weight (diff - minus or ratio)
2,2 -diff entries for wight (diff - minus or ratio)

Thanks for the commit! The unit tests passed successfully.

Here are some comments on the implementation based on the screenshot:

• Data Proportions: The proportions for the data should remain unchanged. However, the height for the "Weight" version should be increased by approximately 1.15 (or 15%).
• histoXYweight Entries Column: I believe it would be more appropriate to use a 2D representation for the entries column, specifically "entries:X". Currently, it's displayed in 3D as "entries vs Y vs color(X)". My preference is to maintain the same X-axis for both visualizations.
• Diff Plot X-Axis Title: If possible, please ensure the X-axis title in the diff plot matches the title used above.

All tests are OK

There are many warnings - related to the unit test

• 44 passed, 403 warnings in 71.65s (0:01:11)

After adding pytest.ini with unit test the amount was reduced to the 53

• 44 passed, 53 warnings in 61.38s (0:01:01)

I will commit the pytest.ini after merging

I briefly reviewed the code and did not identify any obvious issues.

We will need to develop a new unit test in which we prepare specialized data and define invariants to facilitate easier testing of self-consistency.

I am merging the pull request, but the issue remains open for now.
