SANSA_Coagulation_Overlapping_Size_Distributions

This version of SANSA is an attempt to make the code more robust by
generalizing the
coagulation routine to accept overlapping size distributions for each
source. Previous model trials evaluated non-overlapping size
distributions. Condensation is commented out in this version of SANSA to
focus on coagulation. This version of the code is from Laura Posner and
is current as of January 30, 2014.
