Function which takes as input a matrix with 2 columns and a vector indicating left points of intervals [b, Infinity) and checks whether each interval in the matrix is contained within the corresponding interval derived from b.
Alargerb(A, b)
Matrix of size (nrow(A) * length(b)) with binary values indicating whether the intervals in A are contained in the ones induced by b
Two column matrix containing intervals to be checked for being contained in b
Vector indicating left point in corresponding [b, Infinity) interval
