Changes in version 1.6.0:

    o   Restructured the CyData class for simplicity and internal fields.

    o   Deprecated plotCell* functions, renamed them to plotSphere*.

    o   Added the createColorBar() convenience function.

    o   Removed the diffIntDist() function.

    o   Restored option for quantile normalization in normalizeBatch().
	 Switched to deterministic algorithm for sampling when mode="warp".

Changes in version 1.4.0:

    o   Bug fix to interpreSpheres() when making additional plots.

    o   Switched to custom colour calculation in plotCellIntensity().

Changes in version 1.2.0:

	 hyperspheres.

    o   Exported multiIntHist() for plotting multiple intensity histograms.

    o   Slight fix to spatialFDR(), which now computes the correct n-th
