ListMap

java.lang.Object
- com.fr.stable.ListMap<K,V>

所有已实现的接口:

java.io.Serializable, java.lang.Cloneable, java.util.Map<K,V>
```
public class ListMap<K,V>
extends java.lang.Object
implements java.util.Map<K,V>, java.lang.Cloneable, java.io.Serializable
```
让Map的Key是顺序的. This class combines the utility of the HashMap & the ListSet. Features are: 1) Ensure quick random access to an object using a 'key' 2) Iterate through the Map in the order in which the entries were made
