Description:  Summarizes CrossBlock results.
Used for testing and validating CrossBlock.

Usage:  summarizecrossblock.sh in=<input file> out=<output file>

Standard parameters:
in=<file>           A text file of files, or a comma-delimited list of files.
                    Each is a path to results.txt output from Crossblock.
out=<file>          Output file for the summary.
overwrite=f         (ow) Set to false to force the program to abort rather than
                    overwrite an existing file.

Processing parameters:
None yet!

Java Parameters:
-Xmx                This will be passed to Java to set memory usage, overriding the program's automatic memory detection.
                    -Xmx20g will specify 20 gigs of RAM, and -Xmx200m will specify 200 megs.  The max is typically 85% of physical memory.
-eoom               This flag will cause the process to exit if an out-of-memory exception occurs.  Requires Java 8u92+.
-da                 Disable assertions.
