Fix default string values with floats for float types

Summary:

String default are used in place of float for float types for plotters.

This affects the implementation of the "Plotter Editor" especially at the creation of the spinboxes that checks strictly for the correct type

Relevant isse(s) fixed:

Fixes #15 (closed) (closed)

Part of beat.editor#181 (closed)

Part of beat.tutorial.prefix!1 (merged)

This issue was noted for algorithms, but a proper fix could not be set as they affect v1 versions of the algorithms.

For plotters, this shouldn't be a problem though.

Reminder: Once this is merged, we need to fix that on the production platform too.

Note:

This has been corrected in https://gitlab.idiap.ch/beat/beat.tutorial.prefix/ too (beat.tutorial.prefix!1 (merged))

Just for posterity's sake, !21 (merged) documents what was wrong with fixing it for algorithms. And yes, I think it's fine for plotters since those are controlled by us on the platform for now...has this been tested with beat.web?

@samuel.gaist : your input on @jdiefenbaugh's question ?

@andre.anjos : ping. Once the above question is answered we can merge I guess

What question ? Whether it has been tested on beat/beat.web> ? I personally haven't done any specific checks with regards to this. I am expecting the fixer to do the necessary tests before submission.

OK, so merging...

merged
