Computes the Shapley value (n indices) of a set
function. The set function can be given either under the form of an
object of class set.func, card.set.func or Mobius.set.func.
Methods
object = "Mobius.set.func"
The Shapley value is computed from the M<c3><b6>bius transform of a set function.
object = "card.set.func"
The Shapley value is computed from a cardinal set function.
object = "set.func"
The Shapley value is computed from a general set function.

## a set function
mu <- set.func(c(0:13/13,1,1))
## the Shapley value
Shapley.value(mu)
## the efficiency property should be satisfied
sum(Shapley.value(mu))
## a similar example using a Mobius.set.func object
a <- Mobius(mu)
Shapley.value(a)
## a similar example using a card.set.func object
mu <- upper.capacity(6)
Shapley.value(mu)
## the efficiency property should be satisfied
Shapley.value(mu)*6
