Description

In this task, we put in place the titan 0.5.4 implementation of the graph database abstraction layer. As part of this effort, the existing "titan" maven project will be merged into this new project, since it is specific to titan 0.5.4. The maven projects in Atlas that depend on the "titan" will be changed to depend on the new project. Direct dependencies on titan 0.5.4 will be removed from all of the atlas projects. These projects will be changed to depend on this new project instead. They will transitively obtain the dependencies on titan 0.5.4 that they need. For this task, very little of the existing Atlas java / scala code will be changed. The classes from in the titan project will be moved verbatim into the new project. The only other changes will be the addition of the new classes that implement the abstraction layer interfaces.
