- Usage:
`wtgrev=grevlexWeight(wtR)`

- Inputs:
`wtR`, a weight matrix

- Outputs:
`wtgrev`, a matrix, grevlex-over-weight matrix

i1 : wtR = matrix{{5,6,6},{3,6,0}}; 2 3 o1 : Matrix ZZ <--- ZZ |

i2 : grevlexWeight(wtR) o2 = | 1 0 0 | | 5 6 6 | | 3 6 0 | 3 3 o2 : Matrix ZZ <--- ZZ |

It is not standard in algebra systems to have a weighted monomial ordering based on one row of weights such as matrix{{5,6,6}} extended to matrix{{1,1,0},{1,0,0},{5,6,6}}, While M2 could extend it to matrix{{1,1,1},{1,1,0},{1,0,0},{5,6,6}} fairly easily, the method here allows for more than one independent row of a matrix matrix{{5,6,6},{3,6,0}} to be extended to matrix{{1,0,0},{5,6,6},{3,6,0}}.
