Provider to Region has and belongs to many relationship

[dcollie2]

Summary

Providers can serve many regions and regions can have many providers. This will have use in the UI later--and possibly in the XML delivered downstream.

Dependency

Regions and providers should be created before doing this.

Approach

We initially planned a ProviderRegions table but since there are a limited number of regions and they are not likely to change frequently, we're shifting our approach.

Criteria for Completion

• Region belongs to provider
• Provider has many regions
• UI when editing provider allows association of multiple regions
• Testing in place
