:mrdocs:

Remove from this `JsonObject` the `Member` object having the specified `key`, if it exists, and return 1; otherwise (there is no object with a key equivalent to `key` in this `JsonObject`) return 0 with no other effect. This method invalidates only iterators and references to the removed element and previously saved values of the `end()` iterator, and preserves the relative order of the elements not removed.
