Overview
CostFunctions are used with a Trainer to determine how close a Network is coming to its target. CostFunctions are functions of two variables.
To get a cost function instance use the included FromName#from_name. Then you can #call or #derivative any cost function.
To create a new cost function that can be used with a Trainer, you must call FromName#register and implement the #call and #derivative class methods.
