Beefed up influx client README

[derailed]

Left what was already there, but added much needed code samples to showcase the client API.

Great stuff. We should also add some files in the client package for example_test.go and put in appropriate examples so they show up in the generated GoDoc as well.

An example of how that is done is here:

https://github.com/golang/go/blob/439b32936367c3efd0dadab48dd51202e1a510f1/src/net/url/example_test.go

This can be done under a separate pull request as well.

straightforward is one word.

Thanks @derailed -- this is very helpful. We just need some copy changes, and to make it clear there is no default user in 0.9, and we should be good to go. Don't forget the CLA.
