/**
* This class represents the main Octane context. This context represents the following:
*
*
* - Octane server
* - Sharedspace id
* - Workspace id
* - Authentication object
*
*
* This represents the following URL in the Octane REST API:
*
*
* {@code server_url:port/api/shared_spaces/[sharedspace_id]/workspaces/[workspace_id]}
*
* However if both the sharedspace and workspace ids are omitted the context will be assumed to be the space admin:
*
*
* {@code server_url:port/api/shared_spaces}
*
*
* If only the workspace id is omitted the context is assumed to be workspace admin
*
*
* {@code server_url:port/api/shared_spaces/[sharedspace_id]}
*
*
*
* The {@code Octane} class is instantialized using the {@link Octane.Builder} class. Once that instance has been
* obtained the Octane context can be used to create further entity, metadata, attachment contexts or to sign out of the server.
*
*
* The Octane instance can be reused to create different contexts
