Heat map from equal length x,y,z vectors

Provides an interface to use image by providing three equal length vectors for x, y and z coordinates.

image_xyz( x , y , z , ... )

`x`	vector of x values
`y`	vector of y values
`z`	vector of z values
`...`	other parameters to pass to `image`

This function merely constructs a matrix suitable for image, using x, y and z coordinates.
