TINKERPOP-1310: Allow OLAP to return properties as Detached
https://issues.apache.org/jira/browse/TINKERPOP-1310
I created {{HaltedTraverserFactoryStrategy}} which is an OLAP strategy that
can return {{DetachedXXX}} elements to the user instead of always just the
plain (data-less) {{ReferenceXXX}}. Also did lots of nick nack optimizations
and documentation to {{TraversalVertexProgram}}.
CHANGELOG
```
* Added `HaltedTraverserFactoryStrategy` to allow users to get back
different element detachments in OLAP.
```

TraversalVertexProgram can use DetachFactory or ReferenceFactory when
sending halted traversers to the master traversal. The default is to use
ReferenceFactory (more efficient), but if someone wants to use DeatchedFactory,
then they do
g.withComputer().withStrategies(HaltedTraverserFactoryStrategy.detached()).
Easy peasy lemon squeezy. Still need to write specific test cases, but manual
testing shows things workings.

lots of more documentation on TraversalVertexProgram and I really combed
through the code and was able to find numerous minor optimizations here and
there.
