In dMod: Dynamic Modeling and Parameter Estimation in ODE Models

Transform matrix A into reduced row echelon form this function is written along the lines of the rref-matlab function.

1	rref(A, tol = sqrt(.Machine$double.eps), verbose = FALSE, fractions = FALSE)

`A`	matrix for which the reduced row echelon form is searched
`tol`	tolerance to find pivots
`verbose`	logical, print verbose information
`fractions`	logical, not used right now.

a list of two entries is returned; ret[[1]] is the reduced row echelon form of A, ret[[2]] is the index of columns in which a pivot was found
