In EMMAgeo: End-Member Modelling of Grain-Size Data

#' Start GUI for EMMA
#' 
#' This function starts a browser-based graphic user interface for EMMA. The 
#' GUI has so far been tested on a Linux system, both with the browser of 
#' RStudio and Mozilla Firefox. It permits basic access to import, display 
#' and model a user-provided data set.
#' 
#' To use own data set, this should be a plain ASCII file with samples 
#' organsised as rows and grain-size classes organised as columns. The ASCII 
#' file can be separated by spaces, commas, semi colons or tab stops. The 
#' file may contain a leading column with sample IDs and/or one leading row 
#' with grain-size class breaks. To run EMMA make sure that there are no 
#' classes that contain only zeros throught all samples (i.e., remove them 
#' beforehand, e.g., by \code{X = X[,colSums(X) > 0]}).
