context_page_description: The Loader-Content-Handler-Handler, or "LCHH", is a web programming architecture that is closely modeled after the HTTP request-response cycle and the 3-tier web structure.
  As its name suggests, LCHH defines four key implementation components:
  The Loader is an ID'ed DIV container that identifies a partial update region for later content injection;
  The Content that contains both static information and interactive elements, also known as "Triggers";
  Client-side Handlers that process various trigger events, such as button clicks;
  Server-side Handlers that respond to AJAX requests that are sent by the client-side handlers. Server-side handlers typically perform database CRUD operations before piggy-backing the updated content into the aforementioned Loader.
