Remove superfluous comments

Use '^\s+//\ \~\ .*$' and '^\s+//\ ============+$' regular expression
searches to remove superfluous comments.

Prior to this commit, many classes would have comments to indicate
blocks of code (such as constructors/methods/instance fields). These
added a lot of noise and weren't all that helpful, especially given
the outline views available in most modern IDEs.
