into the per-experiment event scheduler for the experiment underneath
the sliver. An example of how to use this is the new test script
called injectevent.py, which you run like:

users> injectevent.py now geni1-program start COMMAND='/bin/ls >& /tmp/foo'

which injects an event for the program agent on your geni1 node.

Note that you have to contact the specfic CM for the node; if you have
multiple nodes spread across several CMs, you have to call this method
at the CM where the node lives.
