This module is toolbox for operating on types and it's declarations. It should simplify required operations.

• Use flat object to extract type or declaration hierarchy into stream so it can be searched or filtered.

  value stringflatHierarchy = flat.types(`String`);
  assert(stringflatHierarchy.containsEvery([`SearchableList<Character>`,`List<Character>`,`Comparable<String>`,`Object`]));
  
  value stringflatHierarchy = flat.declarations(`class String`);
  assert(stringflatHierarchy.containsEvery([`interface SearchableList`,`interface List`,`interface Comparable`,`class Object`]));
