#1 Path dependency

[Antony Quinn]

Have to specify files relative to Jetty/Tomcat
top-level directory. Any way to pass in relative
location, eg. webapps/das? Can then do replace in
properties file eg. GO.uri=${context.dir}/go.obo. Or
better...
- call back so calling class can handle: callee should
return input stream

Added InputStreamListener. Changed Dogwood so returns stream
using ServletContext.

HOWEVER...

only works for TabOntology files because DAG-Edit does it's
own stream access. For now, we will have to use a workaround
(namely, specifying the path in the properties file) if we
want to use local ontology files. Remote and absolute paths
are OK. Given the size of the JARs, it might be worth
getting rid of DAG-Edit altogther and writing our own simple
parser.
