Constructs an object of type T and wraps it in a std::unique_ptr.
1) Constructs a non-array type
T. The arguments args are passed to the constructor of T. The function does not participate in the overload resolution if T is an array type. The function is equivalent to:
unique_ptr<T>(new T(std::forward<Args>(args)...))
2) Constructs an array of unknown bound
T. The function does not participate in the overload resolution unless T is an array of unknown bound. The function is equivalent to:
unique_ptr<T>(new typename std::remove_extent<T>::type[size]())
3) Construction of arrays of known bound is disallowed.

[edit] Parameters
| args | - | list of arguments with which an instance of T will be constructed.
|
| size | - | the size of the array to construct |
[edit] Return value
std::unique_ptr of an instance of type T.
[edit] Exceptions
Any exception thrown by the contructor of T. If an exception is thrown, this function has no effect.
