Tidied up repo, and allowed blurring to be added pre-decomposition

Now, to add scripts that:
i) Decompose a single image with many different blurrings, and
ii) Decompose a single image with many different nmax
Written script to decompose over multiple blurrings - seems to work

	new file:   decompose_single_ASCII_multiple_blur.py
Added README
	new file:   README.md
Written a second script to decompose the same image multiple times with different
maximum orders of decomposition

	new file:   decompose_single_ASCII_multiple_nmax.py
