Counts the features in a QgsVectorLayer in task.

You should most likely not use this directly and instead call
|

:py:func:`QgsVectorLayer.countSymbolFeatures()` and connect to the signal
|
|
:py:func:`QgsVectorLayer.symbolFeatureCountMapChanged()`.

Create a new feature counter for ``layer``.

:param context: Specific QgsExpressionContext to use during the rendering step.

:param storeSymbolFids: If ``True`` will store the feature ids (fids), otherwise will only count the number of features per symbol. Default ``False``.
