Eliminate drand48 #318
Description
@s6pepaul fixed a bug from an unseeded use of drand48 in the BreitWignerGenerator with this PR #317
There are several more uses of drand48 in halld_sim https://github.com/search?q=repo%3AJeffersonLab%2Fhalld_sim%20drand48&type=code
Some may be deprecated, but we should just clean them all up to replace with a TRandom which is properly seeded from the generator.
