[Zodb-checkins] SVN: ZODB/branches/3.4/src/transaction/interfaces.py Removed a "self" argument. self is normally not shown in interfaces.

[Jim Fulton]

Log message for revision 30161:
  Removed a "self" argument. self is normally not shown in interfaces.
  
  Removed the freeme argument.  This argument is part of the
  implementation, not the public interface.
  
  Removed the subtransaction argument.  Although it is still supported,
  it isn't part of the pblic interface.
  
  Added missing documentation of the savepoint method.
