+The first example has a very complex nested container type, which demonstrates the power of this library. Look at the simpler examples below to understand it better. The example adds an element into the data structure, and then accesses it. The type used, with c++ template syntax is:
**CHashMap**< **CString**, **CHashMap**< *int*, **CList**< **CArray2**< *float* >>>>
Note: The *chash_sm_destroy(&theMap)* call below, will destroy all the nested containers including the memory allocated for CString keys in theMap object.
