Title: Add parallel downloading for increased speed. Closes #4

Use the [multiprocessing module](http://docs.python.org/2/library/multiprocessing.html) to create a pool of workers and make it possible to download multiple finding charts simultaneously. The pool has as many workers as CPUs there are in the system. For example: two images are downloaded concurrently if we have two CPU cores our machine.
