(5) Added the ability to export coregistered images and heterogeneity images; Fixed a bug where the colormap was not being calculated correctly when using the exportImage window; Fixed a bug in the "getNumOfSlices" for heterogeneity images with NaN values; Moved the heterogeneity colormap from the "updateImagePanels" function to a separate file; Changed the viewCoregistration function to use double values between 0 and 1 so that the image can be normalized to anything;
