##' @title QGIS algorithm - Import text table
##'
##' @param TABLE `vectorDestination` - Table. Path for new vector layer.
##' @param HEADLINE `boolean` - Headline. 1 for true/yes. 0 for false/no. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
##' @param SEPARATOR `enum`  of `("(0) tabulator", "(1) ", "", "(2) ,", "(3) space", "(4) other")` - Separator. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
##' @param ENCODING `enum`  of `("(0) ANSI", "(1) UTF-7", "(2) UTF-8", "(3) UTF-16 (Little Endian)", "(4) UTF-16 (Big Endian)", "(5) UTF-32 (Little Endian)", "(6) UTF-32 (Big Endian)", "(7) default")` - Encoding. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
##' @param SEP_OTHER `string` - Separator (other). String value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
##' @param FILENAME `file` - File. Path to a file.
##' @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`.
