iskConvexGame checks if a TU game is k-convex. A TU game is k-convex if and only if its k-cover exists and is convex. See section 7.1 of the book by Driessen for more details

1	iskConvexGame(v, k)

`v`	Numeric vector of length 2^n - 1 representing the values of the coalitions of a TU game with n players
`k`	An integer specifying k

TRUE if the game is k-convex, else FALSE

# Two examples motivated by the book by T. Driessen, p. 175:
#
# The following game is 2-convex 
library(CoopGame)
alpha = 0.4
v=c(0,0,0,alpha,alpha,0,1)
iskConvexGame(v,2)

# The following game is not 2-convex
