1.  case class AppliedDiffGraph(diffGraph: DiffGraph, nodeToTinkerNode: HashMap[IdentityHashWrapper[NewNode], Vertex]) extends Product with Serializable

   Diff Graph that has been applied to a source graph.

   Diff Graph that has been applied to a source graph. This is a wrapper around diff graph, which additionally provides a map from nodes to graph ids.

2.  class Converters extends AnyRef
3.  abstract class CpgPass extends AnyRef

   Base class for CPG pass - a program, which receives an input graph and outputs a sequence of additive diff graphs.

   Base class for CPG pass - a program, which receives an input graph and outputs a sequence of additive diff graphs. These diff graphs can be merged into the original graph ("applied"), they can be serialized into a binary format, and finally, they can be added to an existing cpg.bin.zip file.

   A pass is provided by inheriting from this class and implementing run, a method, which creates the sequence of diff graphs from an input graph.

   Overview of steps and their meaning:

   1. Create: A sequence of diff graphs is created from the source graph 2. Apply: Each diff graph can be applied to the source graph 3. Serialize: After applying a diff graph, the diff graph can be serialized into a CPG overlay 4. Store: The CPG overlay can be stored in a serialized CPG.

4.  class DiffGraph extends AnyRef

   A lightweight write-only graph used for creation of CPG graph overlays

   A lightweight write-only graph used for creation of CPG graph overlays

   The graph can store edges to/from nodes that do not exist in the base graph. It doesn't assign ids for these nodes until the diff graph is serialized. Ids of new nodes may collide with ids of nodes in the base graph, which are not sources or destinations of edges of the diff graph. When the CPG loader adds nodes of the overlay, it therefor needs to reassign ids for nodes if they are already used in the original CPG.

   TODO Michael: make DiffGraph extend tinkerpop.Graph to simplify and foolproof the model
