Travis doesn't support cpu affinity in their virtuals so I've added a setting TESTING that will bypass the actual affinity setting, but will still cover most of the code.
Might be useful for future workarounds.
The core module was becoming too large.
By splitting it in cluster, monitor and tasks it becomes more manageable. It also reflects the documentation structure.
Workers now share a ctype with the sentinel to indicate if they are currently executing a task. This timer is incremented each guard loop until the worker resets it after finishing a job or until it reaches the TIMEOUT value and the worker is terminated by the sentinel.
