/**
 * A 'class' representing generic currency conversion functionality for deal matrices.
 *
 * Follows a convention based approach for identifying cells that require conversion.
 * Rather than a single synchronous conversion, the approach taken is to split the work required up into
 * logical sections (known henceforth as 'deal blocks') and returning control to the browser momentarily between
 * deal block conversions.
 *
 * The convention is as follows:
 *
 *           _________________________________________________________

 *
 * Blocks that relate to the same currency are encapsulated in DIV elements with an ID of 'currencyGroup'
 * and a name of 'currencyGroup'. Cells within a 'currencyGroup' are further subdivided into logical units known
 * as 'deal blocks'. These are denoted by DIV elements with a name of 'dealBlock'. Each 'deal block' is processed
 * synchronously. After processing a deal block, the next block is scheduled for processing at a later stage
 * (denoted by the TIME_BETWEEN_DEAL_BLOCKS parameter defined below). This approach is taken so that control can be
 * returned to the browser between conversions, allowing continual response to the user for large pages.
 *
 * Each rate cell within a deal block is expected to contain semi-structured data:
 *
 *   ---> <span name="drc">[currencySymbol]RATE</span>
 *  (the currencySymbol is optional, but cannot contain digits).
 *
 * To provide further flexibility, users of this class can schedule callbacks for various phases in the lifecycle:
 *
 * before any conversions take place: addPreConversionCallback(function() { ... } );
 *
 * before each currency group: addPreCurrencyGroupCallback(function(...) { ... } );
 *
 * after each currency group: addPostCurrencyGroupCallback(function(...) { ... } );
 *
 * before performing cell conversions on each deal block: addPreDealBlockCallback(function(...) { ... } );
 *
 * after performing cell conversions on each deal block: addPostDealBlockCallback(function(...) { ... } );
 *
 * after entire conversion: addPostConversionCallback(function() { ... } );
 *
 * These callbacks can be useful in performing various random tasks (i.e. updating messages pertaining to currency
 * codes).
