#' @title The FELLA package
#' 
#' @description 
#' \code{FELLA} is a metabolomics data enrichment tool that contextualises 
#' a list of metabolites using KEGG reactions, 
#' enzymes, modules and pathways [Picart-Armada, 2017]. 
#' 
#' @details
#' \code{FELLA} can build knowledge models for the desired organism 
#' from the KEGG database [Kanehisa, 2017]. 
#' Once a model is ready, the input for the enrichment is introduced 
#' as a list of affected metabolites (as KEGG IDs). 
#' The output contains a comprehensive biological network layout 
#' that relates relevant pathways to the affected metabolites. 
#' Results are available in network and tabular format. 
#' 
#' \code{FELLA} is equipped with a simple graphical interface 
#' for the lay user, deployed through \link{launchApp}.
#' 
#' \code{FELLA} relies mainly on the following packages: 
#' KEGGREST for the queries 
#' to the KEGG server [Tenenbaum, 2013], 
#' \pkg{igraph} for the 
#' network support [Csardi, 2006] and 
#' \pkg{shiny} for the 
#' graphical user interface [Chang, 2017].
