made the readme lines only 80 characters long and removed double spaces....

... I have some questions on a few of the items. I will make those on github.
I don't think this is the proper location for that. We will need to create proper documentation for the PyNE website (see, e.g. http://pyne.io/latest/usersguide/material.html). This is where we will need to put the dictionary description and all the usage directions. You can leverage cross referencing. For things that make sense to have as code, you can point from the manual to the examples and things that make sense to have as written documentation you can point from the examples to the website.
