+ * Map handlers/updaters for NMS.
+ *
+ * These are functions used to determine how the map should look in NMS.
+ * They represent vastly different information, but in a uniform way. I
+ * suppose this is the c++-type of object orientation...
+ *
+ * The idea is that these updaters only parse information that's fetched by
+ * NMS - they do not request additional information. E.g., ping data is
+ * always present, but until the ping-handler is active, it isn't
+ * displayed. This might seem redundant, but it means any handler can
+ * utilize information from any aspect of NMS, and thus opens NMS up to the
+ * world of intelligent maps base don multiple data sources.
