class GoodData::Bricks::UndotParamsMiddleware
Converts params from double underscore notation to nested hash under ‘config’ Parameters starting GDC_ are considered system params and aren’t converted.
This is useful because the executor platform can currently do just key-value parameters. Also it makes it easier for a user, as there aren’t as much curly braces.
### Examples If you pass params in form: {“my__namespace__param”: “value”}
you’ll get: {“my”: {“namespace”: {“param”: value}}}
