Blurry!

Added optional blurring functionality as a replacement for inconsistent clarity. The result image can now be viewed with interpolation between the data-points to give a smoother image.

Bug Fixes/Enhancements

• fixed a reshaping bug where the row and column dimensions were swapped with data in the correct order
• colour mapping has now been systematically tested, allowing arbitrary intensity or colour-mapping of the input values to the image pixels
