    Summary:
     Duplicating node in graph

    Expected Behavior:
     Upon selecting a node and pressing Ctrl+D, the node will be duplicated

    Test Steps:
     1) Open Script Canvas window (Tools > Script Canvas)
     2) Open a new graph
     3) Add node to graph
     4) Duplicate node
     5) Verify the node was duplicated6) Verify the node was duplicated

    Note:
     - This test file must be called from the Open 3D Engine Editor command terminal
     - Any passed and failed tests are written to the Editor.log file.
        Parsing the file or running a log_monitor are required to observe the test results.
