Version of LGPL used is not documented

[GoogleCodeExporter]

Outside of the rather vague statement that the license is the LGPL, there is no 
indication of which version of the LGPL this code is being released under.

pom.xml contains a link to the top level LGPL page, which is *currently* 3.0, 
but that could change any time the LGPL changes, since it always points at the 
most recent release.

Proper licensing methodology is to have a file of some sort in the source tree 
that contains the explicit version of a given license the code is being 
released under, so that there is no guesswork involved.  At the least, please 
update pom.xml to directly note which version of the LGPL this code is being 
released under.
