Should exclude Javadoc

[sebbASF]

Javadoc is generated, so no point flagging it

Better, it should be configurable whether to scan javadoc. Maybe an 'ignore path' config parameter.

[sebbASF]

Not sure why one would ever want to scan Javadoc as well as the source from which it is generated.
There is already a way to ignore paths, but it means every project with Javadoc has to update their config.

[julianhyde]

Agreed, virtually no one wants to scan javadoc. But neither do you want the tool skipping directories because it wrongly thinks they contain javadoc.

[sebbASF]

The tool should anyway list which directories are skipped.

Note that Javadoc directory trees have a standard set of files, so should be reasonably easy to detect with few false positives
