+ * Helper class to build a dictionary of hit parameters and values.
+ * <br>

+ * id<GAITracker> t = // get a tracker.
+ * [t send:[[[GAIDictionaryBuilder createEventWithCategory:@"EventCategory"
+ *                                                  action:@"EventAction"

+ *     set:@"dimension1" forKey:[GAIFields customDimensionForIndex:1]] build]];
+ * </code>
+ * This will send an event hit type with the specified parameters
+ * and a custom dimension parameter.
+ * <br>
+ * If you want to send a parameter with all hits, set it on GAITracker directly.
+ * <code>
+ * [t set:kGAIScreenName value:@"Home"];
