exclude directory

It would be a nice have an exclude feature to omit directories when javancss generates the report.
This could follow the standard maven style.
For example
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>javancss-maven-plugin</artifactId>
<version>2.0-beta-1</version>
<configuration>
<excludes>
<exclude>*/binding/*</exclude>
<exclude>*/persistence/*</exclude>
<exclude>com/example/dullcode/*/.class</exclude>
<exclude>com/example/**/*Test.class</exclude>
</excludes>
</configuration>
</plugin>
