Unique Indices will fail for some user input

[radex]

because of this:

    function UniqueIndex(uniqueField) {
      this.keyMap = {};
    };
    /* snip */
    UniqueIndex.prototype.get = function (key) {
      return this.keyMap[key];
    };

collection.by(key, xxx) cannot have any unsanitized xxx input or it might fail. For example, this.keyMap['hasOwnProperty'] will always be truthy.

One simple solution is to use Object.create(null) instead of {}, so that the object has no prototype.
