## Purpose: Converts a single branch.log containing multiple benchmark branch outcomes into
##          separate files, one for each program.
## Input:   branch log file generated by modelsim
## output:  outputs to directory branch a collection of files with the branch outcomes
##          separated by benchmark application.  Example names are aha-mot64bd_sizeopt_speed_branch.log
##
## A component of the CORE-V-WALLY configurable RISC-V project.
