We don't really need to add boost headers at all, since noncopyable is simplest
and tidy to implement by ourself:
```
namespace boost {
class noncopyable
{
protected:
noncopyable() {}
~noncopyable() {}
private:
noncopyable( const noncopyable& );
noncopyable& operator=( const noncopyable& );
};
}
```
