This package contains different kinds and implementations subtyping interface Sort.
Each logic term has an assigned a sort. In order to support special concepts like
arrays, objects, primitive types, it is useful to support different kinds of sorts.
This allows to distinguish diffent categories of terms by looking on the sort type
rather than on the name.
In KeY we distinguish formulas from terms by the special sort instance
Sort.Formula.
