Purpose
Create and add a new row to a problem.
This function is similar to xprs_addrow but instead of returning the prob object, it returns the index of the newly created row.
Synopsis
xprs_newrow(prob, colind, rowcoef, rowtype, rhs, name = NULL, rng = NULL)
Arguments

The problem to which the row is to be added.
colind 
The variable indices for the variables in the new row.
rowcoef 
The coefficients for the variables in the new row.
