Implementation of (Int|Float)[Input|Spinner] (New Bokeh widgets)

[xavArtley]

Int, Float separation or not separation?

• Need to update documentation

[philippjfr]

I think we should be consistent about it so I'm happy to make sure we introduce distinct Int/Float widgets throughout.

Please do a rename while you are at it to IntInput and FloatInput as the Spinner name is just confusing. I always thinks is something indicating progress. That's what it is in all other frameworks I know of.

[xavArtley]

For me spinner is the right name for the i put with arrows https://en.m.wikipedia.org/wiki/Spinner_(computing) . In this PR there is already Int and Float Input widget (if no step is given) and an Int and Float Spinner if step is defined.
if there is a consensus to change the name, I would.

[philippjfr]

I think Spinner on it's own is indeed confusing but IntSpinner and FloatSpinner actually resolve the ambiguity for me.

[philippjfr]

I think we've now agreed that we should do the renaming from Spinner -> NumberInput in #1566. So could you start by renaming FloatSpinner and IntSpinner to FloatInput and IntInput in this PR? (If you're short on time I can do it).

[xavArtley]

@philippjfr, I'm a bit short on time, I'll be glad if you could do it.
Thanks
