12 Atoms are special Pegex rules that represent the small pieces of text
13 that you can use to build up regular expressions. Usually they are one
14 or two characters.

16 It may seem like a waste of time to specify "COLON" in a regex, instead
17 of a simple ":". There are three reasons this is encouraged. First is
18 that you are defining a grammar for a new language, and it is worth the
19 time to be clear and verbose. Second, using an abstraction like this
20 can help with portability to languages with different regex engines.
21 Finally, it makes the grammar for Pegex so much simpler, because a "/"
22 is always a part of the Pegex syntax, and a "SLASH" is part of your
23 grammar.
