Incremental cost-utility function

h(Delta_C,Delta_QALY) = ICUR

Maps incremental cost and incremental quality-adjusted life years to the additional cost per QALY gained.

Incremental cost-utility ratio
```
ICUR = Delta_C / Delta_QALY
```
Calculates the additional cost per additional quality-adjusted life year when ratio interpretation is appropriate.
