##' @title QGIS algorithm - Unique value statistics for grids
##'
##' @param GRIDS `multilayer` - Values. .
##' @param MAJORITY `rasterDestination` - Majority. Path for new raster layer.
##' @param MINORITY `rasterDestination` - Minority. Path for new raster layer.
##' @param NUNIQUES `rasterDestination` - Number of Unique Values. Path for new raster layer.
##' @param ... further parameters passed to `qgisprocess::qgis_run_algorithm()`
##' @param .complete_output logical specifying if complete out of `qgisprocess::qgis_run_algorithm()` should be used (`TRUE`) or first output (most likely the main) should read (`FALSE`). Default value is `TRUE`.
##' @param .quiet logical specifying if parameter `.quiet` for `qgisprocess::qgis_run_algorithm()` Default value is `TRUE`.
##' @param .messages logical specifying if messages from `qgisprocess::qgis_run_algorithm()` should be printed (`TRUE`) or not (`FALSE`). Default value is `FALSE`.
