LaserPlasmaSource.h

This class describes a laser-generated plasma source, and can create pairs
with the specified distribution. It is specified as a region which propagates in 
a specified direction.

1.0  (JohnV 06-13-00) Original code.
1.1  (Bruhwiler 09-25-00) Modified to work in r-z geometry.
1.2  (Bruhwiler 10-04-00) added ability to delay start of laser pulse
