Get the class or interface name of the
@see reference. The name is fully qualified if the name specified in the original
@see tag was fully qualified, or if the class or interface can be found; otherwise it is unqualified. If
@see references only a package name, then return the package name instead. For example, for:
@see String#valueOf(java.lang.Object)
return "java.lang.String". For "
@see java.lang", return "java.lang". Return null if
@see references a non-element, such as
@see <a href="java.sun.com">.
