[Xastir] Sub-grid Shape Files for Individual Grid Squares

[Eric Germann]

As promised, I've made available sub-grid shape (.SHP) files for each of
the 32,400 grid squares.  These can be found at
http://www.n1ics.net/node/15 under Maidnehead shape files.

They are organized in a tree based on the first 4 characters of the grid
square, for easy browsing and download.

I have created a SourceForge project to host the entire collection of
shape files.  I will announce the URL for that once it is approved.
