Fix license/copyright information

Hello.

I updated the license/copyright information. I didn't change any code of any sort, I simply made the license file more concise and clear. At the bottom of the Apache license you will find the following paragraph: 

To apply the Apache License to your work, attach the following boilerplate
notice, with the fields enclosed by brackets "[]" replaced with your own
identifying information. (Don't include the brackets!) The text should be
enclosed in the appropriate comment syntax for the file format. We also
recommend that a file or class name and description of purpose be included on
the same "printed page" as the copyright notice for easier identification within
third-party archives.

See http://www.copyright.gov/circs/circ01.pdf for more info.

I removed the extra license information that is found at the included website and included just what Apache requested be included in the license, and updated the copyright year to 2014, since only copyright years listed in the current year are valid per: http://www.copyright.gov/circs/circ01.pdf.

Thanks!
