fix typo
Merge pull request #253 from mpollmeier/patch-1

fix typo
added cyclicPath and simplePath asciidoc documentation with two new images.
moved TimeLimitStep to filter/. I don't know why it was in sideEffect/. Fixed up docs with new ProfileStep -p option.
updated CHANGELOG and fixed URL x.y.z issue in docs.
added UnionStep, UnionLinearStrategy, CapTraversal (for the cap() method like count() and CountTraversal). Merged in @rjbriody TraversalHelper.hasStepClass() to try and make Stragegy execution as fast as possible.... no need to make lists if they will simply be empty. Fixed #73
added union() step documentation to asciidoc with new image.
added a good toString() for UnionStep and fixed up the UnionTest a bit.
big change to make Traverser API naming according to the query languge rule. Traverser.loops(), Traverser.bulk(), Traverser.path(). Etc. Updated tests. Updated docs. Lots of stuff changed.
Fixed a major bug around Arrays.binarySearch(). Have a test case now that verifies proper behavior. Fixed #250
consistency around label names of dynamically created steps in linear strategies.
Expand tests around hiddens #251
greatly simplified TraversalVertexProgram again. No need for a TraverserPathTracker and a TraverserCountTracker. With TraverserSet being the underlying data structure now, its just TraverserTracker. Much much simpler code -- especially in TraverserMapReducer. Stoked.
More tests for consistency in hiddens #251.

Made the neo4j implementation pass these tests.

Added Element.graph() and renamed Property.getElement() to Property.element(). Greatly simplified GiraphInternalVertex by reducing the memory footprint by 50% and reducing the construction time. Found this via working with @dalaro ... Added TraverserSet to GremlinKryo as now TraverserTracker is basically solely on TraverserSet -- no more Map representation. Fixed #199
Path.getObjects() and Path.getLabels() is now Path.objects() and Path.labels() to be consistent with new query lanugage naming convention. Fixed a change I shold not have done to giraph-kryo.properties.
