Consider multiple facility types with varying maximum distance measures

[chrisnatali]

We want to allow users to define what "Covered" means in terms of different facility types each with their own maximum distance metric.

Example:
2 health facility types: Clinic (demand should be within 1km) and Hospital (demand should be within 10km) How many facilities of each type would be required to satisfy demand such that no demand node is further than 1km from either facility type AND no further than 10km from a Hospital?

Actually, this should be cost based. We want to minimize cost of coverage given different facility types with different capacities and different maximum distances.
