Bureaucracy Manager

A software system able to guide and assist clients that try to progress
through the mind-numbing procedures of a classic bureaucratic system. A configuration
specifies the existence of an arbitrary number
offices and any number of documents which may be required by
customers. No documents may be obtained directly; to
receive it, the customer must obtain a number of intermediate documents.
The offices feature queues, and some offices have more than one counter for
working with the public. At any time, a situation may occur where any of the counters
be temporarily closed because of important
coffee breaks. The application must simulate the whole system, based on a
Configuration information containing at least the following elements:

- Offices and documents issued by them
- Dependencies between documents (which documents are needed to receive another
document)

Customers will be simulated by threads.
