Description:  Creates tree.taxtree from names.dmp and nodes.dmp.
These are in taxdmp.zip available at ftp://ftp.ncbi.nih.gov/pub/taxonomy/
The taxtree file is needed for programs that can deal with taxonomy, 
like Seal and SortByTaxa.

Usage:  taxtree.sh names.dmp nodes.dmp merged.dmp tree.taxtree.gz

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.  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.

Please contact Brian Bushnell at bbushnell@lbl.gov if you encounter any problems.
