Initialize cobertura plugin structure
copy/paste from project specific logic
Since we are now writing a plugin with it's own module.ivy file we could remove the ivy:cachepath task in cobertura:init and add it as a dependency
Easyant automatically creates a classpath specific for each plugin, this classpath contains all the required dependency <i>.jars</i>.

The classpath is named
<code tyep="xml">
[organisation]#[module].classpath
</code>
Example:
<code type="xml">
org.apache.easyant.plugins.cobertura.classpath
</code>
Since this classpath is auto-created you can use it to reference your taskdef.
document properties used by the plugin
Add include/exclude options
