Overview:
A library for classifying isolated hypersurface singularities w.r.t. right
equivalence, based on the determinator of singularities by V.I. Arnold.


Procedures:
* basicinvariants:: computes Milnor number, determinacy-bound and corank of
* classify:: normal form of poly f determined with Arnold's method
* corank:: computes the corank of f (i.e. of the Hessian of f)
* Hcode:: coding of intvec v according to the number repetitions
* init_debug:: print trace and debugging information depending on int n
* internalfunctions:: display names of internal procedures of this library
* milnorcode:: Hilbert poly of [e-th] Milnor algebra coded with Hcode
* morsesplit:: residual part of f after applying the splitting lemma
* quickclass:: normal form of f determined by invariants (milnorcode)
* singularity:: normal form of singularity given by its name s and index
* swap:: returns b,a
* A_L:: shortcut for quickclass(f) or normalform(s)
* normalform:: normal form of singularity given by its name s
* debug_log:: print trace and debugging information w.r.t level>@DeBug
