 Overview:
 A library for computing the Sagbi basis of subalgebra through Sagbi walk
algorithm.
 Theory:
 The concept of SAGBI ( Subalgebra Analog to Groebner Basis for Ideals)
is defined in [L. Robbiano, M. Sweedler: Subalgebra Bases, volume 42, volume
1430 of Lectures Note in Mathematics series, SpringerVerlag (1988),6187].
The Sagbi Walk algorithm is the subalgebra analogue to the Groebner Walk
algorithm which has been proposed in [S. Collart, M. Kalkbrener and D.Mall:
Converting bases with the Grobner Walk. J. Symbolic Computation 24 (1997),
465469].
