 <div class="block"><b>Purpose</b>: To allow object level transactions.  This class represents the public API of the
  unit of work and should be used to maintain complete compatibility.
  <p>
  <b>Description</b>: The unit of work is a session that implements all of the normal
  protocol of an EclipseLink session. It can be spawned from any other session including another unit of work.
  Objects can be brought into the unit of work through reading them or through registering them.
  The unit of work will operate on its own object space, that is the objects within the unit of work
  will be clones of the original objects.  When the unit of work is committed, all changes to any objects
  registered within the unit of work will be committed to the database.  A minimal commit/update will
  be performed and any foreign keys/circular reference/referential integrity will be resolved.
  If the commit to the database is successful the changed objects will be merged back into the unit of work
  parent session.
  <p>
  <b>Responsibilities</b>:
  <ul>
  <li> Allow parallel transactions against a session's objects.
  <li> Allow nested transactions.
  <li> Not require the application to write objects that is changes, automatically determine what has changed.
  <li> Perform a minimal commit/update of all changes that occurred.
  <li> Resolve foreign keys for newly created objects and maintain referential integrity.
  <li> Allow for the object transaction to use its own object space.

  be committed, nor will changes be merged into the global cache.
  <p>
  A subsequent commit (on UnitOfWork or global transaction) will be required to finalize the commit process.
  <p>
  As the commit process has begun any attempt to register objects, or execute object-level queries will
  generate an exception.  Report queries, non-caching queries, and data read/modify queries are allowed.
  <p>
  On exception any global transaction will be rolled marked or marked rollback only.  No recovery of this UnitOfWork will be possible.
  <p>
  Can only be called once.  It can not be used to write out changes in an incremental fashion.
  <p>
  Use to partially commit a transaction outside of a JTA transaction's callbacks.  Allows you to get back any exception directly.
  <p>
  Use to commit a UnitOfWork in two stages.</div>
