Check if a particular entity is contained in a catalog.

Unlike Catalog.contains(...), this function can checks multiple catalogs to validate transitive containment.

Scenario:

• Site 00a's Catalog contains Initiative 00b.
• Initiative 00b's Catalog contains Project 00c.
• Project 00c's catalog contains Dataset 00d.

Problem: Validate that 00d should be displayed in the context of 00a.

Logic:

• Check if 00d is contained in 00c's catalog
• Check if 00c is contained in 00b's catalog
• Check if 00b is contained in 00a's catalog If all three are true, then 00d is considered contained in 00a's catalog.
