slack(A, rows)

slackdir(A, rows)

`A`	Coefficient matrix.
`rows`	Index of rows which are _not_ equality constraints. If left blank, all are assumed to be inequality constraints.

This operation comes in two flavors, goverened by functions slack() and slackdir(). For the former, given a coefficient matrix A and an index of rows rows, this will return the coefficient matrix with slack variables added appropriately. The latter does the same, but for extreme direction problems; in particular, it adds the constraint for the sum of the d's.
