Complex types and equality from natives.galaxy

// -- Complex types and equality --
//
// Normally, comparing two "complex" objects with the == or != operators will only compare the
// object reference, not the contained object data.  However, a few types will compare the contained
// data instead.  These types are:
//
//      abilcmd, point, string, unitfilter, unitref
//
// Examples:
//
//      Point(1, 2) == Point(1, 2)                              // True
//      "test string" == "test string"                          // True (note: this is case sensitive)
//      AbilityCommand("move", 0) == AbilityCommand("move", 0)  // True
//      Order(abilCmd) == Order(abilCmd)                        // False (two different order instances)
//      RegionEmpty() == RegionEmpty()                          // False (two different region instances)
