`erase` overloads

== Synopses

Declared in `<bslstl_map.h>`

Remove from this map the `value_type` object at the specified `position`, and return an iterator referring to the element immediately following the removed element, or to the past‐the‐end position if the removed element was the last element in the sequence of elements maintained by this map. This method invalidates only iterators and references to the removed element and previously saved values of the `end()` iterator. The behavior is undefined unless `position` refers to a `value_type` object in this map.

Remove from this map the `value_type` object whose key is equivalent the specified `key`, if such an entry exists, and return 1; otherwise, if there is no `value_type` object having an equivalent key, 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.

Remove from this map the `value_type` objects starting at the specified `first` position up to, but including the specified `last` position, and return `last`. This method invalidates only iterators and references to the removed element and previously saved values of the `end()` iterator. The behavior is undefined unless `first` and `last` either refer to elements in this map or are the `end` iterator, and the `first` position is at or before the `last` position in the ordered sequence provided by this container.
