+/**
+ * A {@link ResourceCalculator} which uses the concept of  
+ * <em>dominant resource</em> to compare multi-dimensional resources.
+ *
+ * Essentially the idea is that the in a multi-resource environment, 
+ * the resource allocation should be determined by the dominant share 
+ * of an entity (user or queue), which is the maximum share that the 
+ * entity has been allocated of any resource. 
+ * 
+ * In a nutshell, it seeks to maximize the minimum dominant share across 
+ * all entities. 
+ * 
+ * For example, if user A runs CPU-heavy tasks and user B runs
+ * memory-heavy tasks, it attempts to equalize CPU share of user A 
+ * with Memory-share of user B. 
+ * 
+ * In the single resource case, it reduces to max-min fairness for that resource.
+ * 
+ * See the Dominant Resource Fairness paper for more details:
+ * www.cs.berkeley.edu/~matei/papers/2011/nsdi_drf.pdf
