Coordinate Array macro

[Michael Doube-2]

Hi All,

I've just released a new macro, which is designed to correlate
mineralisation density information from an SEM image of bone and
cartilage to nanoindentation modulus from a UMIS nanoindentation array.

It reads a set of coordinates from a CSV file, then the user defines
(0,0), (xmax,0) and (0,ymax) key positions in the image, based on marker
indents in the image. (xmax,ymax) must be on the last line of the CSV
file.  The macro can scale, rotate, shear and reflect the coordinates
based on the key positions. It then allows you to step through each
indent forwards [l] and backwards [j], or go to any indent in the array
[g]. You can draw all the coordinates with [y] (although I haven't quite
got batch mode to work properly for this). You can measure some
variables (mean grey, median grey, area fraction) and classify tissue
with [t].

If anyone has suggestions on how to improve the code or wants to borrow
bits of it, they are most welcome.
