2%CS_LSOLVE solve a sparse lower triangular system L*x=b.
3%   x = cs_lsolve(L,b) computes x = L\b, L must be lower triangular with a
4%   zero-free diagonal.  b must be a column vector.  x is full if b is full.
5%   If b is sparse, x is sparse but the nonzero pattern of x is NOT sorted (it
6%   is returned in topological order).

8%   Example:
9%       Prob = ssget ('HB/bcsstk01') ; L = cs_chol (Prob.A) ; n = size (L,1) ;
10%       b = rand (n,1) ; x = cs_lsolve (L,b) ; norm (L*x-b)
