.Concept.Simple Type:
..summary:Object that does not need constructors, destructors or copy assignment operators.
..description:
All POD ("plain old data") types are simple types, but some simple types are not POD types, e.g. the subclasses of @Class.SimpleType@.
A simple type can have constructors, destructors or copy assignment operators,
but it can be proper default constructed without using a default constructor, destructed without calling the destructor and copied without calling a copy constructor or a copy assignment operator.
Hence, simple types can be handled by fast memory manipulation functions.
This greatly speeds up functions like @Function.arrayCopy@.
..remarks:
...text:If you want specify a custom type $MyClass$ to be simple, then just specialize the @Metafunction.IsSimple.IsSimple metafunction@:
...code:template <>
struct IsSimple<MyClass>
{
    typedef True Type;
};
