Detailed Description

A thread pool similar to the thread pool in the UPnP SDK.

Allows jobs to be scheduled for running by threads in a thread pool. The thread pool is initialized with a minimum and maximum thread number as well as a max idle time and a jobs per thread ratio. If a worker thread waits the whole max idle time without receiving a job and the thread pool currently has more threads running than the minimum then the worker thread will exit. If when scheduling a job the current job to thread ratio becomes greater than the set ratio and the thread pool currently has less than the maximum threads then a new thread will be created.
