+    application if it wishes.  Data can be hashed on an integer or string key.

+    Example:
+    @code
+        wxHashTable table(wxKEY_STRING);
+
+        wxPoint *point = new wxPoint(100, 200);
+        table.Put("point 1", point);

+
+    A hash table is implemented as an array of pointers to lists.
+    When no data has been stored, the hash table takes only a little more space
+    than this array (default size is 1000). When a data item is added, an integer
+    is constructed from the integer or string key that is within the bounds of the array.
+    If the array element is @NULL, a new (keyed) list is created for the element.
+    Then the data object is appended to the list, storing the key in case other
+    data objects need to be stored in the list also (when a 'collision' occurs).
+
+    Retrieval involves recalculating the array index from the key, and searching
+    along the keyed list for the data object whose stored key matches the passed key.
+    Obviously this is quicker when there are fewer collisions, so hashing will
+    become inefficient if the number of items to be stored greatly exceeds the
+    size of the hash table.
