Visualforce Controller Class Convention

A quick post to outline an informal convention for the definition of a Visualforce controller class, key maintainability characteristics being predictable structure, readability and prominent revision history. All developers have a subjective preference in this regard, however consistency is key, particularly in the Salesforce context where multiple developers/consultancies contribute to a codebase over its lifetime. A simple, logical approach always makes sense to maximise adoption.
