When allocating a new event, if the same name is used, no allocation is
created and NULL is returned. We start trying to use the returned value
which seg-faulted. I added a check to only continue if the returned value
from the allocation is not NULL.
refs #149
After further discussion, it was revealed that the event printouts would stop
coming out if a new event was created. Found that the constructor of the
event was clearing out the static info_msg flag all events used to test
for printing. Removed the assignment in the constructor and set the
initial value of the info_msg flag to false at the declaration point.
Fixes#38
Changed all header file once include variables to follow the same naming
convention and not start with any underscores. Also deleted old
incorrect copyright notices. Also removed $Id: tags from all files.
Fixes#14. Fixes#22.
