Fix for 2 output variables that were not initialized properly.
Enabled the exposure monitor. Needed to increase Dejagnu's buffer size again.
These 2 tests were flawed. They depended on a unit being slated for destruction on day 3 but then having an outgoing direct contact on day 4, which violated this statement from the model spec: "Units are also quarantined when they are placed on the prioritized waiting list for destruction ... Quarantined units cannot be involved in direct contact". The tests have been rewritten to use indirect contact.
