start_point: start point
In walkr: Random Walks in the Intersection of Hyperplanes and the N-Simplex

Given Ax ≤ b, which defines a convex polytope, this function picks n random starting "center" points using linear programming.

1	start_point(A, b, n = 1, average = 10)

`A`	is the lhs of Ax ≤ b
`b`	is the rhs of Ax ≤ b
`n`	is the number of points we want to return
`average`	is the number of boundary points we want to take the average of

a matrix, with each column as a point

A <- rbind(c(-1, 0), c(0, -1), c(1, 1))
b <- c(0, 0, 1)
