intern

This library implements the InternPool as described on the page javax0 article. It is capable interning objects. Interned objects in a pool are represented with a single instance when they are equal. Thus

   a = pool.intern(a)
   b = pool.intern(b)

will become a == b if a.equals(b) was true before interning even if a == b was not true before interning.

The library is thread safe.
