A new function sm1_slope is added.
This function evaluates of the slopes of a given system of linear
differential equations.  The slope is used to detect irregularity.
Examples are also given.

The function slope computes the slopes of a given D-module.
It uses the ACG algorithm (Assi,Castro,Granger, How to calculate
the slopes of a D-module, Compositio Math (1996), 107--123) to
get the algebraic slopes.  In order to get the geometric slopes,
the ACG algorithm should be modified and repeated use of radical
computation is necessary.  Radical computation is done by ox_asir
module via OpenXM connection.
This module is a joint work with Castro-Jimenez.
