TITLE: TSCHK2 memory leak

DESCRIPTION OF BUG:
Valgrind shows a memory leak from tschk2 version 2.1.0.

Two files for the libtouchstone memory leak are included.  One is the text 
output of valgrind showing the memory leaks.  The other file is a test Touchstone 
file to reproduce the issue.

To reproduce the issue, run this command on a Red Hat Linux machine:

valgrind --show-reachable=yes --show-error-list=yes --leak-check=full bin/tschk210_linux_64/tschk2 INOUT.s2p

From the valgrind output, there are three memory leaks.  Each one is a “loss record”.

INSERT TOUCHSTONE FILE DEMONSTRATING THE BUG:

Supporting files are found in the https://ibis.org/bugs/tschk/bug7 directory:
- tschk2_valgrind_output.txt - valgrind output
- INOUT.s2p - test Touchstone file
