Log:
multiple contact birth/death time can be defined as a curve 

________________________________________________________________________________

After 12/7/08, DT is hardwired to 1e+20 during DR so that if contact
 becomes active during DR, it remains active for the remainder of the DR.
 If DR is input as negative, it still has the effect of making contact inactive
 during DR.  The summary below does NOT reflect this update.

_______________________________________________________________________
cymbals1.k  BT+  DT+    contact is active from BT to DT in both DR and transient

cymbals2.k  BT-  DT+    contact is active from |BT| to DT for DR; 
                        contact is active from 0 to DT in transient

cymbals3.k  BT+  DT-    contact inactive for whole DR since DT is negative;
                        contact is active from BT to |DT| during transient 

cymbals4.k  BT-  DT-    contact inactive for whole DR since DT is negative;
                        contact is active from 0 to |DT| during transient 
                         (negative BT in this case has same effect as BT=0)


Note contact is always killed at t=|DT|, in both DR and transient phases
