Licensing

[jkbest2]

If we're going to publish this code so that others can use it, we need to pick a license. Hadley's run-down on licensing here:

And the full list of licenses that can be used for CRAN packages here:

https://svn.r-project.org/R/trunk/share/licenses/license.db

My understanding is that the GNU General Public License (GPL) version 2 or 3 are most often used for R packages (and R itself is under GPL-2 or GPL-3). This would be a fine choice for us. Another option that allows the end-user more flexibility is the MIT license.

@grantdadams this is something we should discuss with Alex at our upcoming meeting.
