<!-- ##### SECTION Title ##### -->
Combo autocompletion object

<!-- ##### SECTION Short_Description ##### -->
Provides autocompletion based on frecuency and time. Popup list changes
with each autocompletion action to provide a related list from which
to choose.

<!-- ##### SECTION Long_Description ##### -->
<para>
The autocompletion combo object uses a dbh file to tabulate frecuency of access
and time of access of strings. These strings must be null terminated. The 
autocompletion will build a list with the latest access string first, followed 
by strings in descending frecuency of access order. This list will be displayed
and autocompletion is done on that basis. Only the first elements of the list
are shown in the popup.
