Scavenger - Now With History Based Profiling

I have just added yet another scheduler to Scavenger (yes, there is three of them now). This scheduler is the "smartest" of the three as it uses history based profiling in order to be able to choose the right surrogate for the job. History based profiling in a cyber foraging system is nothing new - the Chroma system used that some 6-7 years ago. What is new is the way that the profiling information is used within the Scavenger system. In Scavenger the profiling information can be used not only to tell you something about how the task will perform on certain surrogates (i.e., the ones where you have earlier performed the task), it is also capable of making an informed estimate of the running time on an unknown surrogate... more on that later ;-)
