<P>
An SCADomain that starts a Tuscany runtime supporting multiple
 SCA contribution jars. All contribution jars found in a repository
 directory will be contributed to the SCA domain. Any changes to the
 contributions in that repository will be automatically detected and
 the SCADomain updated accordingly.
 
  TODO: find how to properly add/remove contributions and start/activate the SCADomain
  TODO: support contributions that are folders as well as jar's
  TODO: needs to restart the entire SCADomain when a contribution changes
        as the domain classpath includes all the contribution jar's, would
        be nice to find a way to avoid this
  TODO: hot update requires copying contribution jars to a temp location
        to avoid the classpath lock preventing updating the contribution
        jars, would be nice to find a way to avoid that

<DL>
<DD>Copies Files to a temp location returning the URLs of the new temp files.
 For hot update to work need to be able to delete/update the contribution jar's
 but as they're in the classpath the URLClassLoader has an open lock on the jar's
 so you can't update them. This solution copies each contribution to a temp
 location for use on the classpath, nicer would be a ClassLoder impl that doesn't
 lock the jar's.

<DD>Checks if any of the contributions have been updated and if so restarts the SCADomain
 TODO: Ideally just the altered contribution would be restarted but thats not possible
       as the ClassLoader used by the SCADomain includes the old contribution so need
       to restart the entire domain to use a new ClassLoader. Should there be separate 
       ClassLoader per contribution? But then have all the issues with sharing classes
       across contributions.
