/*
 * First block: section 4A
 * 
A) Test a transitively closed subsystem deploys no transitive resources
 - Register repository R1
 - Using the Root subsystem, install a scoped subsystem with the following content bundles and no local repository
   - Bundle A
   - Bundle B
   - Bundle C
   - Bundle D
   - Bundle E
 - Verify the wiring of C, D and E wire to A->x, A, B->y respectively
 - Verify no new bundles are installed into the Root subsystem (particularly bundles F and G)
