How to run the web interface
----------------------------

### Bring up database server

Assuming you've created the database in some location such as `/path/to/db`,
run the db server using something like `rosrun mongodb wrapper.py
_database_path:=/path/to/db`.  If you're running multiple instances of the db
server on the same machine, you can set the `warehouse_port` ros parameter to
use different ports.

### Bring up web server

Run the web server using `rosrun semantic_model_web_interface run_server.py`.
This brings up the site on port 5000 of the local machine.  You can use a
different port by passing it as the single argument to `run_server.py`.  The
server will look at the `warehouse_port` ros parameter to decide which port to
look for the db on (defaults to 27017).
