1.1.1
    - Added functionality to plot differentially-enriched KEGG pathways using software package pathview
    - Added interactive plotting function to generate comparisons of many lists at once using PCA and dendrogram plots
    - Added several example datasets of .bed files from He, A. (2011).
1.1.2
    - Included static vignette for illustration purposes. Some steps in our pipeline require either writing to disk or the use of a registered email, which are difficult to include in a dynamically-compiled vignette. Using a vignette that is able to show each of the steps in the pipeline with a helpful degree of detail is better than having a dynamic but less expressive one.
    - The vignette included uses the example datasets from He (2011) to run through the entire pipeline, illustrating the major steps and providing a useful template for analysis.
1.1.3
    - Added ability to plot absolute values of Z-scores in plotZScores()
    - Fixed vignette to include Abs() plotting
