Feature/fuzzy match

Works both directly on the attributes of a record and attributes
of (nested) relation of the record.

Due to filtering on these relations, the change was a bit more
complex.

The adapter instance needs to be passed down the whole chain of
matching, since extra queries need to occur to walk the path of
relations.

Extra Notes

leaf must refer to attribute

It somewhat assumes the last leaf in the path refers to an attribute
of a record. If it ends in a relation, this won't provide the results you
want as a user.

This will work:

store.find('user', undefined, {
  fuzzyMatch: {
   name: 'john D',
   'address:building:rooms:roomName': 'Room X'
   }
  }
)

This not:

store.find('user', undefined, {
  fuzzyMatch: {
   name: 'john D',
   'address:building': 'Building Y'
   }
  }
)

interface in the options object

The options object

  fuzzyMatch: {
   'name': 'john D',
   'address:building:name': 'Building Y'
   }
  }

might be debatable. I understand

  fuzzyMatch: {
    name: 'john D',
    address: {
      building {
        name: 'Building Y'
      }
     }
  }

is more uniform. But adds some complexity implementation wise. Let me know what you think.

I think a proper fuzzy match would use a string distance metric, but this will do lol.
