    alternative splicing quantification
    * Minor UI improvements

        contextual information for the selected cut-off (below the slider)
        - Improve how alternative splicing quantification is assigned to
        patients based on their samples
    * Protein annotation:
        - Warn user when trying to render proteins with no domains

1.0.5 (7 Jan, 2017)

        - Improve speed when calculating total contribution of each variable to
        the principal components
    * Survival analysis:
        - Shorten calculation of optimal PSI that minimises the survival
        difference
        - Improve visual cues of optimal PSI cut-off and present p-value of 
        selected PSI cut-off
        - Fix ambiguous error messages
        - Fix incorrect Cox model results for formula-based calculations
        - Fix null Cox models crashing the program
    * Differential splicing analysis:
        - Select sample types for differential splicing analysis
        - Fix statistical tests not displaying for individual events after
        differentially analysing all events using the other statistical tests
