int	size () const
	Returns the number of elements in the Map.
Object	operator[] (string)
	Returns the item at the given key, creating an undefined Object if the key does not yet exist in the map.
void	clear ()

Detailed Description

Maps strings to Objects.

ChaiScript has a built in shortcut for generating Map objects:

Example:

eval> var m = ["a":1, "b":2];
[<a,1>, <b,2>]
eval> m.count("a");
1
eval> m.count("c");
0
eval> m.size();
2

Implemented as std::map<Boxed_Value>
