multi agents defined in the qiao conf

[matarrese]

Hi @ytung05 , can you have a look on this new pull request? As we discuss in the previous pull request, in this new one, as you recommended, to set up the program it requires changes only in the qiao.xml configuration file. For the impact of the modification, I had to change quite a lot of classes and because I'm not familiar with all the components of the project I took some assumption and decisions that they should be reviewed carefully. Please let me know your thoughts

Thanks Antonia. Review in progress...

The new PR is on the right path. Excellent efforts!

1. Let us ingest file-manager, book-keeper, and others as properties to an agent in qiao.xml, so it doesn't look crowded. Keep detailed bean level configurations in beans.xml. For example,

..

2. Use for setting doneFileHandler and/or quarantineFileHandler in PatternMatchFileInjector for consistency. They should reference to those defined at the agent level.

3. Use the same formatter. It is hard for reviewers to find the changes in the code if a different formatter is used. I will email you the formatter if you use eclipse.
