Added `isi()` and `cv_isi()` functions.
Switched from Markdown to reStructuredText for README file.
Merge pull request #3 from toddrjen/master

update .gitignore
Merge branch 'master' of github.com:apdavison/elephant
Extended statistics functions to accept plain NumPy arrays as well as SpikeTrains.
Renamed "ElePhAnT" to "Elephant"
Now using numpydoc Sphinx extension.
Removed `cv_isi()` function, added `cv()`.

`cv_isi(spiketrain)` can be replaced by `cv(isi(spiketrain))`. Note that this adds a dependency on `scipy`, but I think that is a reasonable dependency for this package.
Removed the remaining instances of "ElePhAnT"
I thought `rescale()` was in-place, but it isn't.
