allow easier recursive file processing with File.eachFileRecurse { ... }

There's an interesting discussion here...

http://wiki.codehaus.org/groovy/FileSupport

one thought was recursive deletion...

def recursiveDelete(File file) {
outer = this
if( file.isDirectory() ) {
file.eachFile

{ outer.recursiveDelete(it) }

}

file.delete()
}

I wondered if we should have a recursive file method where you could do

new File("/home/foo").eachFileRecurse

{ println it.name }

which would iterate through all files recursively like the above - calling children first before parents.

Then a recursive delete would be

file.eachFileRecurse

{ it.delete() }
