Linear fitter on the client

[pl0xz0rz]

This PR adds linear regression on the client to RootInteractive.

This PR also:

• Enables using multiselect for parameters
• Fixes an infinite loop in javascript in case of cyclic dependency between custom defined columns

This isn't finished, and some features are missing:

• fitterArray to automatically create aliases, without having to use transformArray and aliasArray

How to use

parameterArray = [
    {"name": "predictors", "value":["X1","X2"], "options":["X1", "X2", "X3",  "Custom"]}
]
jsFunctionArray = [
    {
        "name": "fitterY",
        "type": "linearFit",
        "varX": "predictors",
        "varY": "Y",
        "alpha": 1,
       "weights":"W",
       "source": None # If using the main source for fitting, this is optional
    }
]
aliasArray = [
    {
        "name": "YPred",
        "variables": "predictors",
        "transform": "fitterY"
    }
]
widgetParams=[
    ['multiSelect', ["predictors"]]
]

EDIT: Ridge regression and weights are working now

Observations: In some tests looks like callbacks are broken, histograms do not react to changes in selection.

• RootInteractive/RootInteractive/InteractiveDrawing/bokeh/test_BokehClientHistogramQuantile.html
• RootInteractive/RootInteractive/InteractiveDrawing/bokeh/test_BokehClientHistogramRowwiseTable.html
  • here we see that selection is doing something in the tables we see changes but not in the figures
  • looks like callback for drawing can be broken

Problem looks to be there only for some dashboards.

The test on Linux test servers at GSI can not be done. Farm should be back next week. Will we wait or do we merge?
