Add LICENSE

This is mostly a direct copy of the Charm++ license, but I've modified it slightly to apply to Projections.

Here's the output of a diff (some of the changes are trimming trailing whitespace in the original):

A few questions should be answered before merging:

• The last line specifies a number for the license. Is that number specific to Charm++, or can it be reused for Projections?
• The license specifies that it was approved by Illinois counsel. Does this need to be reviewed again by the appropriate counsel or is this approval valid for this copy of the license, too?
• Projections depends on a couple LGPL licensed libraries (FreeHEP and JFreeChart). We don't ship either with the source code (the dependencies are specified in the build.gradle file and are downloaded at build time). Does that need to be reflected in the license anywhere? As far as I can tell, we should be fine shipping these libraries, but a second opinion would be good.

This might be interesting for 7.0. Here is a slightly updated diff to the Charm++ license :
