ComputeAlphas_j_a_o
PURPOSE 
Computes the set of al possible alpha-elements.
SYNOPSIS
function As=ComputeAlphas_j_a_o(P,V)
DESCRIPTION
Computes the set of al possible alpha-elements.
Compute the whole se of alpha_j_a_o elements.
This function only works for POMDP with discrete action and observation
spaces.
The function is a generic implementation that uses the particular
ComputeAlpha_j_a_o function of the corresponding type of POMDP.
Parameters
P: The POMDP.
V: The previous policy/value function/set of alpha-elements.
