[Moller] halla12_software emaillist

[Zhiwen Zhao]

Hi, folks

I setup a halla12_software emaillist
https://mailman.jlab.org/mailman/listinfo/halla12_software

For now it will be mainly used for moller and solid simulation. Later on 
for calibration, reconstruction etc and even other halla12 project.

Any relevant update will be distributed through solid and moller 
emaillist also.

cheers

Zhiwen
