public static final class ScriptGroup.Builder extends Object
First all the Kernels to be used by the group should be added. Once this is done the kernels should be connected. Kernels cannot be added once a connection has been made.
Second, add connections. There are two forms of connections. Kernel to Kernel and Kernel to Field. Kernel to Kernel is higher performance and should be used where possible. The line of connections cannot form a loop. If a loop is detected an exception is thrown.
Once all the connections are made a call to create will return the ScriptGroup object.
