[HepMCVisual] quiting HepMC Browser within athena

[Bertrand Chapleau]

Dear authors,

I just discovered HepMC Browser/Visual...what a nice utility ! Thanks  
for providing it.

When running Athena in interactive mode using the HepMC Browser  
jobOption file, if I quit the application by clicking the 'exit'  
button on the gui, the normal stty settings seem not to be restored  
properly...terminal/command line is still in 'raw mode'. To exit  
properly, I have to do a 'ctrl-d' within Athena itself, on the command  
line.

I'm using release 15.2.0 of Athena.

Regards,
Bertrand
