Changes in version 1.3.3                        

    o   plotPromoters is deprecated

    o   Implemented three new functions
	- plotPCA: performs principal component analysis
	- plotHeatmap: heatmap visualization
	- integrateProactiv: integrate different proActiv runs

                       Changes in version 1.1.22                        

    o   Update package-down site

    o   Gene expression data is now stored in the assays of the summarizedExperiment 
	object returned by proActiv to facilitate easier filtering of the 
	summarizedExperiment object. The metadata slot is now empty. 

    o   Plotting promoter activity: Implementation of boxplotPromoters function to 
	plot boxplots of absolute promoter activity, relative promoter activity, and
	gene expression.

    o   Identification of alternative promoters: Implementation of 
	getAlternativePromoters, used to identify promoters that may exhibit alternative
	usage.

                       Changes in version 1.1.15
