Description: Library providing a threading pool where you can add work on the fly. The number
of threads in the pool is adjustable when creating the pool. In most cases
this should equal the number of threads supported by your cpu.
For an example on how to use the threadpool, check the main.c file or just read
the documentation found in the README.md file.
In this header file a detailed overview of the functions and the threadpool's logical
scheme is presented in case you wish to tweak or alter something.

Description: Jobs are added to the job queue. Once a thread in the pool
is idle, it is assigned the first job from the queue (and that job is
erased from the queue). It is each thread's job to read from
the queue serially (using lock) and executing each job
until the queue is empty.
