Check if game is degenerate
Description
Checks if a TU game is degenerate. We call a game essential if the value of the grand coalition is greater than the sum of the values of the singleton coalitions. We call a game degenerate (or inessential), if
v(N) = \sum v({i})
.

Examples

#The following game, i.e. the Maschler game, is not degenerate
library(CoopGame)

isDegenerateGame(v1)
#The following game is also not degenerate
library(CoopGame)
v2 <- c(30,30,15,60,60,60,72)
isDegenerateGame(v2)
#The following game is degenerate
library(CoopGame)
