==Functions==

Some absolute basic functionality that should be provided:
* m[k] or m.get(k) - get the value v associated with key k in map m, returns key error
* m[k] = v or m.set(k,v) or m.put(k,v) - set the value v associated with key k in map m
* del m[k] or m.remove(k) - remove the element with key k in map m
* len(m) or m.size() - return the number of elements (unique keys) in the map
* iter(m) - iterator over keys of map

==Notes==

Base map class. [[Maps]] are essentially key-value data structures - you pass in a key, you get back a value.

In the Java Collections framework, the Map class is the highest-level abstract class - it is actually an interface, not a class.

Java API Documentation for Map class: http://docs.oracle.com/javase/8/docs/api/java/util/Map.html

The base type Map defines a large number of methods - see [[Maps/ADT]] for the full list.
