v0.2.0

Overview:

The changes made in this minor bump are meant to enable n-hop path queries in bgraph.

Changes:

• Modify the returned query results of bgraph so that they include the Gremlin's state
• Add path tracking state to each Gremlin. Since state is returned in the query results a user can use each vertex stored as part of their results. For ex. path highlighting (give me the path between Vertex A and B)
• Add suspend/unsuspend pipetypes: Suspending a Gremlin causes it to go through the remaining pipes without being modified (for example filters or traversals won't apply to suspended Gremlins) until an unsuspend pipe has been called.
• Add repeat/start pipe: Repeat and start pipes allow a user to repeat a portion of the program as many times as they wish.

Considerations:

• Backwards incompatible change has been added here. However, as this is pre-release only the minor version has been updated.
