/**
* Maps from a program element handles to a list of relationships between that element and other program elements. Each element in
* the list or relationships is uniquely identified by a kind and a relationship name. For example, the advice affecting a
* particular shadow (e.g. method call) can be retrieved by calling get on the handle for that method. Symmetrically
* the method call shadows that an advice affects can be retrieved.
*
*
*
* The elements can be stored and looked up as IProgramElement(s), in which cases the element corresponding to the handle is looked
* up in the containment hierarchy.
*
*
* put/get methods taking IProgramElement as a parameter are for convenience only. They work identically to calling their
* counterparts with IProgramElement.getIdentifierHandle()
