/**
5
 * An SMap is a data structure that holds many mappings of objects to objects:
6
 * say, a string to an other string. This can be likened to the Dict structure
7
 * in python, but not fully.
8
 * 
9
 * An SMap is made up of SMapItems, each MapItem holds two pointers to data.
10
 * The first pointer is the key, the secold is the value.
11
 *
12
 * please note that SMaps can be slow and are unordered.
