advanced_search         This method mimics the advanced_search
                        functionality of Colombos. It takes a series of
                        parameters, representing the different settings
                        available on Colombos advanced search and
                        returns a list containing the locustags
                        (gene_names), contrasts and M-values for the
                        current selection.
advanced_search_by_both
                        Accessory function allowing the advanced_search
                        by both g_ids and c_ids
advanced_search_by_contrasts
                        Accessory function allowing the advanced_search
                        by contrast_ids, go, experiment, condition
advanced_search_by_genes
                        Accessory function allowing the advanced_search
                        by gene_ids, go, annotation
getCompendium           This method allows to download/import the full
                        compendium for the selected organism
listAnnotationTypes     This method takes as parameter a string (the
                        nickname of an organism) and returns a
                        character vector corresponding to the currently
                        available annotation type for the selected
                        organism.
listContrasts           This method takes as parameter a single string,
                        representing an organism, and returns a
                        character vector corresponding to the currently
                        available organisms.
listEntities            This method takes a string containing the
                        nickname for the selected organism and a string
                        containing the annotation type and return the
                        available entities
listGenes               This method takes as parameter a single string,
                        representing an organism, and returns a
                        character vector corresponding to the currently
                        available organisms.
listOrganisms           Returns a character vector corresponding to the
                        currently available organisms.
parseCompendium         This method allows importing the full
                        compendium for the selected organism from a
                        local file
quick_search            This method mimics the quick_search
                        functionality of Colombos. It takes a string
                        containg the nickname for the selected organism
                        and a vector of string representing the genes
                        of interest for the specified organism and
                        returns a list containing the locustags
                        (gene_names), contrasts and M-values for the
                        current selection.
