TBD: improve comment Insert the specified `numElements` from the range starting at the specified `fromBegin` of (template parameter) `FWD_ITER` type (or template parameter `SOURCE_TYPE *`) and ending immediately before the specified `fromEnd` sentinels or iterators of (template parameter) `SENTINEL` type (or template parameter `SOURCE_TYPE *`), into the array of elements of type given by the `allocator_traits` class template for (template parameter) `ALLOCATOR`, starting at the specified `toBegin` address, shifting forward the elements in the array by `numElements` positions. The behavior is undefined unless the destination array contains `numElements` uninitialized elements after `toEnd`, `numElements` is the distance between `fromBegin` and `fromEnd`, and the input array and the destination array do not overlap. If a copy constructor or assignment operator throws an exception, then any elements created after `toEnd` are destroyed and the elements in the range `[ toBegin, toEnd )]` will have valid but unspecified values.
