Graph Execution Engine

Graph Execution Engine is used to execute AI application graphs. It accepts multiple graph files as input, and all graphs are executed in same process context. It also needs manifest files as input which includes list of extensions to load. It must list all extensions required for the graph. Registry graph install command can be used to download all required extensions and generate manifest file.
