I have a series of integers l1={{a1,b1},{a2,b2},...{ai,bi}}
I want to label each pair in the series according to the inequality rules 
defined below
such that I get a series of labels l2={n,k,p....}

k   =  A<0  B<0 
l   =  A<0  B=0 
m   =  A<0  B<0 A=B
n   =  A<0  B>0 
p   =  A>0  B>0 
q   =  A=0  B>0 
r   =  A>0  B>0 A=B
Thanks. John
