Implement suggestion to best practice on plugin code structure

[anders-kiaer]

• ./plugin_name_snake_case

  • _layout.py (Dash layout + ID ownership)
  • _callbacks.py (Dash callbacks)
  • _prop_serialization.py ((De)Seralization of prop inputs)
  • _business_logic.py (query database/input for relevant data, and necessary ad-hoc calculations. Testable functions! No dash* import allowed)
  • _plugin.py ( class PluginNameCamelCase(WebvizPluginABC))
  • __init__.py (from .plugin import PluginNameCamelCase)

• Add a couple of comments in each boilerplate/template file to explain purpose.

• Add a link/reference to a webviz-subsurface plugin showing the split for a complex case.

Consideration:

Prevent shorting in file names: i.e. _prop_serialization.py, rather use _property_serialization.py?
