This commit resolves an issue with a GNU grep command using the -P flag. As a result, users without GNU Grep could not use the Perl Regular Expressions flag. This command has been removed and replaced with pcregrep which yields the same results and also allows forward look-aheads. Additionally, the test-files have been added to the .ccignore file so cloning the repository does not cause users to have the test-files in their first commit message. Closes Issue #1
