ArrShiCatalanB    --    Shi-Catalan arrangement of type B with given multiplicities


Syntax 
ArrShiCatalanB(S: RING, k: INT, L: LIST): LIST

Description
This function constructs the Shi-Catalan arrangement of type B in the first k variables of the polynomial ring S with multiplicities L[1] and L[2].

Example 
/**/ use S::=QQ[x,y,z];
/**/ L:=[-1,2];	
/**/ ArrShiCatalanB(S, 2, L);
[x,  y,  x -y,  x +y,  x -1,  y -1,  x -y -1,  x +y -1,  x +1,  x +2,  y +1,  y +2,  x -y +1,  x -y +2,  x +y +1,  x +y +2]
