`erase` overloads

== Synopses

Declared in `<bslalg_arrayprimitives.h>`

TBD: improve comment Destroy the elements of type given by the `allocator_traits` class template for (template parameter) `ALLOCATOR` starting at the specified `first` `first` pointer and ending immediately before the specified `middle` pointer, and move the elements in the array starting at `middle` and ending at the specified `last` pointer down to the `first` pointer. If an assignment throws an exception during this process, all of the elements in the range `[ first, last )]` will have unspecified but valid values, and no elements are destroyed. The behavior is undefined unless `first <= middle <= last`.
