Change configuration

There are two configuration for the DYMGroup and DYMCommandCollection:

Parameter	Type	Default	Description

cutoff	float	0.5	Possibilities that don’t score at least that similar to word are ignored.

Examples

@cli.group(cls=DYMGroup, max_suggestions=2, cutoff=0.7)
def cli():
    pass

... or ...

cli = DYMCommandCollection(sources=[cli1, cli2], max_suggestions=2, cutoff=0.7)
