Summary:
The script valgrind_test.sh runs Valgrind for all tests in the makefile
including leak-checks and outputs the logs for every test in a separate file
with the name "valgrind_log_<testname>". It prints the failed tests in the file
"valgrind_failed_tests". All these files are created in the directory
"VALGRIND_LOGS" which can be changed in the Makefile.
Finally it checks the line-count for the file "valgrind_failed_tests"
and returns 0 if no tests failed and 1 otherwise.
Test Plan: ./valgrind_test.sh; Changed the tests to incorporte leaks and verified correctness
