Latest commit cac943e Oct 24, 2017 @oniofchaos oniofchaos Add frozen_string_literal in all .rb files
I noticed these files all had strings such as "", "  ", "_" that were
allocated each time some common methods were called, over 1000x on a
page in my app. This comment freezes all of these strings such that
they're only allocated once, saving many KB of memory allocation.
