This function allows the user to get the Kolmorogov distance between two equal spots on an array.

1	getDistance(condition1, condition2)

`condition1`	A transformed affymetrix array
`condition2`	A transformed affymetrix array

This function computes the Kolmorogov distance between two affy sets, transformed into probabilities.

A list of distances
