MarionL - initial cut at build files

- initial draft at ant build files
- needed to include servlet-api.jar, but then omit it from war, so put
it in its own directory only used for compile time (but not in
web-inf/lib - which gets deployed)
-the <ant> call to DAO from REST for some reason was inhereting the
properties from REST, so I had to hardcode the paths in DAO and leave
them  as variables in REST.
-most of this code came from just the ANT home page and the simple ant
example as well as the war task example.
