[Halld-offline] switching from src to sim-recon

[Mark M. Ito]

Folks,

The move has been made.

If you happen to attempt to check in stuff to the old location you will 
get an error with phrases like "commit failed" and "path not found".

If you find yourself in that situation David pointed out to me that 
there is an "svn switch" command that might help. It should allow you to 
point your working version to a new directory in the repository.
