Recreated directory inadvertently added to gitignore (#139)

The newest members of the team found import statement errors when first
pulling from master. Concluded that "security" directory had been placed
in gitignore inadvertently. Reinserting "security" directory and the two
corresponding files to prevent the issue from occurring again.
