Create "Workbench API"
The Workbench API is designed to be a high-level interface to querying, creating, and interacting with STIX data. It builds on the explicit "Environment" concept by exposing a set of module-level functions that operate on an implicit, module-level Environment, without requiring users to be aware of the underlying Environment. (This encapsulation allows applications that need to support multiple Environments to do so, but does not require individual users to manage their own Environment).
