This mode provides code completion to the CodeEdit widget.
The list of suggestion is supplied by a CodeCompletionModel.
Code completion may use more than one completion model. The suggestions
list is then filled model per model by beginning by the highest priority as
long as the number of suggestions is lower than
:attr:`pcef.modes.code_completion.CodeCompletion.minSuggestions`.
For example, a python editor will use a smart completion model with a high
priority and use the DocumentWordsCompletion model as a fallback system
when the smart model fails to provide enough suggestions.
The mode uses a QCompleter to provides display the list of suggestions.
Code completion is triggered using ctrl+space or when there is at least
three characters in the word being typed.
