Remove dependency upon Epsilon

[Duncan McGreggor]

Currently txaws.storage depends upon Epsilon for its Time module for it's functions fromISO8601TimeAndDate and fromDatetime. It would be nice to not require folks to install the Epsilon module to use these two functions.

Code reuse is good, why duplicate stuff?

[Duncan McGreggor (oubiwann)]

Code reuse is definitely good, but removing barriers to entry is also good. I'd like for folks not to have to install stuff if they need not. In the case of little-known modules, I'd rather err on the side of duplication than inconvenience...

There isn't a demonstrated problem though: the barrier to entry is an
unquantified amount.

apt-get install python-epsilon

or easy_install Epsilon

will install Epsilon happily and easily.

The way little known modules become well known is being reused a lot.

The problem I have with your example is that it's Linux-centric. Mac OS
X and Windows users need to be thought of as well.

Epsilon is on PyPI, though, and if they have setuptools installed,
getting it is a no-brainer.

My concern is for those wanting to use txAWS who are interested in
taking advantage of an async library but don't have much Python
experience. I would like for the newbies to have as easy an experience
as possible.

However, if they have Twisted installed, they would have had to deal
with other dependencies, so I guess it really doesn't matter.

I'll close this ticket and create a new one for adding a dependencies file.

Ah, the README has the dependencies in it already. Nothing to do.
