Contour plot from equal length x,y,z vectors

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

contour_xyz( x , y , z , ... )

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

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