allow setting and getting the value of an attribute.
The goal of this class is to hide from the user how an attribute is actually set or get to or from a class instance. Implementations of this base class are usually provided through the MakeAccessorHelper template functions, hidden behind an ATTRIBUTE_HELPER_* macro.

[in,out] | object | The object instance to get the value from |
[out] | attribute | A pointer to where the value should be set. |
This method expects that the caller has checked that the input value is valid with AttributeChecker::Check.
Implemented in ns3::EmptyAttributeAccessor, ns3::AccessorHelper< T, U >, and ns3::ObjectPtrContainerAccessor.
