Updates to code for 1.1

Implement hierarchical client architecture with three-tier organization and lazy loading. Generated from raw clients (Previously had 7 files one per client).  Added utility modules (content_utils_highlevel, version_utils_highlevel, node_utils_highlevel) that simplify operations (upload, download, checkin / checkout versioning, node operations, search).
