[Moller_simulation] no MOLLER simulation telecon. tomorrow

[Juliette]

Hey guys,

I would like to cancel the MOLLER simulation teleconference for tomorrow 
because it is Good Friday.  We will have a teleconference at the next 
regularly scheduled time, Friday, April 20th at 3pm.

I have been busy with other things, so I don't have much to report for 
MOLLER for tomorrow anyway.  But some improvements I have implemented 
for the PREx GEANT4 simulation will be easy to implement for the 
mollersim - such as something Wouter had suggested, which is to set the 
materials as NIST or standard G4 materials by using the material name 
from the GDML file, rather than defining all the materials in the GDML 
file.  Also, it is possible to break up the geometry file into pieces 
which could make the GDML description more modular without being forced 
to use the "daughter volume" definition.  Maybe I can have some of this 
implemented for MOLLER by the next meeting and I can describe it.  
Another thing Peiqing had asked about was whether you could define 
surface properties in GDML, and the answer is YES, there are several 
ways and we can talk about what the "right" way would be.

I noticed that the Qweak meeting has moved to Friday at 1-3pm, but I 
think our time should still be okay.

If anyone wants to try to hold an additional meeting next week, let me 
know.

Thanks,

Juliette
