In JanCaha/r_package_qgis: An extension of package "qgisprocess" providing direct R functions for QGIS functions

##' QGIS Algorithm provided by SAGA Next Gen Analytical hierarchy process (sagang:analyticalhierarchyprocess). ---------------- Arguments ----------------  GRIDS: Input Grids 	Argument type:	multilayer TABLE: Pairwise Comparisons Table  	Argument type:	source 	Acceptable values: 		- Path to a vector layer OUTPUT: Output Grid 	Argument type:	rasterDestination 	Acceptable values: 		- Path for new raster layer

##' @param GRIDS `multilayer` - Input Grids. .
##' @param TABLE `source` - Pairwise Comparisons Table . Path to a vector layer.
##' @param OUTPUT `rasterDestination` - Output Grid. 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`.
