== Description

Return a `shared_ptr` object referring to and managing a new `ARRAY_TYPE` object, where `ARRAY_TYPE` is a bounded array. The specified `basicAllocator` will be used to supply a single contiguous region of memory holding the returned shared pointer's internal representation and the new `ARRAY_TYPE` object, and each element in the array is constructed from the specified `value`. If `basicAllocator` is 0, then the default allocator will be used instead.

== Return Value

shared pointer managing a newly created object
