color_kegg_pathway() function using ggkegg to create colored KEGG pathway ggplot objects (instead of using KEGGREST to obtain the colored PNG files, which no longer works #169)visualize_hsa_KEGG function to visualize_KEGG_diagram() to reflect this is now able to handle KEGG pathway enrichment results from any organismvisualize_terms(), visualize_term_interactions() and visualize_KEGG_diagram() functions so that they now return a list of ggplot objects (named by term ID)get_kegg_gsets() function to also use ggkegg for fetching genes per pathway datamagick, KEGGgraph and KEGGREST
get_biogrid_pin() function so that it can now determine the latest version and download/process it from BioGRID (via setting release = "latest", which is now the default behavior)get_kegg_gsets() which now returns KEGG IDs so that the user can convert the returned identifiers using a more appropriate tool (e.g. BioMart) should they wish
