/**

 * This instance filter takes a range of N numeric attributes and replaces them with N-1 numeric attributes, the values of which are the difference between consecutive attribute values from the original instance. eg:

 *

 * Original attribute values

 *

 *    0.1, 0.2, 0.3, 0.1, 0.3

 *

 * New attribute values

 *

 *    0.1, 0.1, -0.2, 0.2

 *

 * The range of attributes used is taken in numeric order. That is, a range spec of 7-11,3-5 will use the attribute ordering 3,4,5,7,8,9,10,11 for the differences, NOT 7,8,9,10,11,3,4,5.
 *

 *

 * Valid options are:

 *
 *
 -R <index1,index2-index4,...>
 *  Specify list of columns to take the differences between.
 *  First and last are valid indexes.
 *  (default none)
