Description
A new evaluator that calculates abs(y'-y) / (1 + abs(y)) should be implemented. The benefit is that this evaluator allows larger errors if the target value is larger.

Review comments:
- Please change "avg(|y'-y| / |y|+1)" to avg( |y' - y| / (|y| + 1)) in the description
- Remove the applyLinearScaling parameter from the static calculate method
- Remove code to set and unset the execution context for the linear scaling parameter
