%Docstring
A collection of utilities for working with parameters when running a processing algorithm.
Parameters are stored in a QVariantMap and referenced by a unique string key.
The QVariants in parameters are not usually accessed
directly, and instead the high level API provided through :py:class:`QgsProcessingParameters`
parameterAsString(), parameterAsDouble() are used instead.
Parameters are evaluated using a provided :py:class:`QgsProcessingContext`, allowing
the evaluation to understand available map layers and expression contexts
(for expression based parameters).
