''' SF_Dictionary
''' =============
''' Class for management of dictionaries
''' A dictionary is a collection of key-item pairs
''' The key is a not case-sensitive string
''' Items may be of any type
''' Keys, items can be retrieved, counted, etc.
'''
''' The implementation is based on
''' - one collection mapping keys and entries in the array
''' - one 1-column array: key + data
'''
''' Why a Dictionary class beside the builtin Collection class ?
''' A standard Basic collection does not support the retrieval of the keys
''' Additionally it may contain only simple data (strings, numbers, ...)
'''
''' Service instantiation example:
''' Dim myDict As Variant
''' myDict = CreateScriptService("Dictionary") ' Once per dictionary
'''
''' Detailed user documentation:
''' https://help.libreoffice.org/latest/en-US/text/sbasic/shared/03/sf_dictionary.html?DbPAR=BASIC
