示例1: UtcDaliPropertyMapMerge
int UtcDaliPropertyMapMerge(void)
{
Property::Map map;
map[ "hello" ] = 1;

// Create another map with the same keys but different values
Property::Map map2;
map[ "hello" ] = 3;
map[ "world" ] = 4;
// Merge map2 into map1, count should still be 2, map values should be from map2
map.Merge( map2 );
DALI_TEST_CHECK( map.Count() == 2 );
DALI_TEST_CHECK( map[ "hello" ].Get< int >() == 3 );

// Create another map with different keys

// Merge map3 into map1, count should increase, existing values should match previous and new values should match map3
