Return a const iterator to the first element with key greater than key.
Return an iterator providing non-modifiable access to the first (i.e., ordered least) value_type object in this map whose key is greater than the specified key, and the past-the-end iterator if this map does not contain a value_type object whose key is greater-than key. Note that this function returns the last position before which a value_type object having an equivalent key could be inserted into the ordered sequence maintained by this map, while preserving its ordering.
const iterator to the upper bound, or end()
