The directory here exists for the submodule called E.

The reason for this strange name is that I used to do this
a lot in ruby:

    alias e puts

So in other words, I would be using "e" rather than puts,
in order to do output onto the commandline.

I also used to have this in another project called AliasE,
but eventually I decided that I should put this right into
the Colours project.
