trait ContactReductionBinResolution:
    .doc: """
A trait for specifying the resolution used when evaluating contacts for reduction between objects.
A high value will keep more contacts, lower will result in more aggressive reduction.
Commonly a value of 2 or 3 will give good result.
Values from 0 to 10 are valid, where a value of 0 means this will be overridden by the ContactReductionBinResolution from Space.
