输出：

Initially,
Count    : 5
Capacity : 16
Values:
-KEY-    -VALUE-
five:    jumps
four:    fox
one:    The
three:    brown
two:    quick

After TrimToSize,
Count    : 5
Capacity : 5
Values:
-KEY-    -VALUE-
five:    jumps
four:    fox
one:    The
three:    brown
two:    quick

After Clear,
Count    : 0
Capacity : 16
Values:
-KEY-    -VALUE-


After the second TrimToSize,
Count    : 0
Capacity : 16
Values:
-KEY-    -VALUE-
