[udig-devel] More selection tools plugin

[Dave S-B <dev-lists@xxxxxxxxxxxxxxxxxxxxx>]

Below is a patch for the extra selection tools plugin in the community 
pages from Alyotech 
(http://udig.refractions.net/confluence/display/COM/More+selection+tools) 
which allows the plugin to work in uDig 1.2 (I'm using M7) if anyone 
else is interested.
