Here's the first set of example code. The TestDriver program uses JAXP for
parser creation. You can download the Crimson parser with support for JAXP from 
http://xml.apache.org/dist/crimson/ To compile and run the sample you just need
to have the crimson.jar file in your classpath.

The TestDriver program is hard-coded to use the enclosed trades.xml file. It
parses and processes the file, then prints a brief summary of some results. You
can modify the trades.xml file to observe changes in the results.

To run the test program with Crimson you just need to execute:

java -cp .:crimson.jar TestDriver

If the crimson.jar file is located in a different directory, you'll naturally
need to use the full path to the jar.
