Benchmarks for yield optimization method. No direct function calls.
Speedup for test size of one 5s source task and eight 10s working tasks is 190s -> 100s.
Optimizer now accepts -g arguments only, without any source file. Very simple implementation.
Fix with bobopt running parallel on the same code. Possibility to pass additional arguments to bobopt when running on benchmark, for example, configuration file.
Folders for benchmarks, more benchmarks would create a mess in VS.
Tweak of prefetch optimization method. Method is now able to attach prefetch calls to the end of box execution, thus for stateless boxes, it says bobox to again schedule box only if there's necessary input.

Gain is 41.5s to 36.5s (cca -5s)
This was just... bad.
Little refactor, 2 classes renamed. Current names are more specific about class functionality.
