Add "excludePaths" per path about grabbit HOT 2 CLOSED

I guess . would effectively be a no-op right (especially if we only allow sub-paths)? If so, I think we could go eitherway. Legal or Illegal.

from grabbit.

To work with specifics; given the following path structure:

/a
/a/b
/a/c

How would you express the following?

1. Get everything in /a
2. Get all children under /a, but not /a itself
3. Get only /a itself, not its children

I expect it would like

1. { "path": "/a" }
2. { "path": "/a", "excludePaths": ["."] }
3. { "path": "/a/." } or { "path": "/a", "excludePaths: ["*"] }
