Constructs new numeric array from various sources.

1) Default constructor. Constructs an empty numeric array.
2) Constructs a numeric array with count copies of default-initialized elements.
3) Constructs a numeric array with count copies of val or *val respectively.
4) Constructs a numeric array with copies of count values from an array pointed to by vals. If this array contains less than count values, the behavior is undefined.
5) Copy constructor. Constructs the numeric array with the copy of the contents of other.
6) Move constructor. Constructs the container with the contents of other using move semantics.
11) Constructs the numeric array with the contents of the initializer list il.
