Introducing "brem"
"brem" stands for "browser regular expression match" (the name is based on "grep"). simply put, it is a browser extension written in javascript designed to highlight all the strings on a page that match a regex provided by the user.
this project was born from a desire for "ctrl+f" to be able to handle regex. maybe it actually can, i don't know. i didn't actually investigate before starting to work on this.
