#' @title Edit APSIM-X file with a replaced soil profile
#' @name edit_apsimx_replace_soil_profile
#' @description Edits an APSIM-X simulation by replacing the soil profile
#' @param file name of the .apsimx file to be edited
#' @param src.dir source directory
#' @param wrt.dir writing directory
#' @param soil.profile a soil profile object with class \sQuote{soil_profile}
#' @param edit.tag default edit tag \sQuote{-edited}
#' @param overwrite default FALSE
#' @param verbose default TRUE and it will print messages to console
#' @param root supply the node postion in the case of multiple simulations such as factorials.
#' @return writes a file to disk with the supplied soil profile
#' @details This function is designed to batch replace the whole soil in an APSIM simulation file. 
#' @note There is no such thing as a default soil, carefully build the profile for each simulation.
