Converts an adjacency matrix into the adjacency list

1	adj2list(A, ac.type = c("Both", "Two", "One"))

`A`	a symmetric unweighted adjacency matrix.
`ac.type`	indicates the anti clustering referral distribution types. Type "Two" is "refer friends based on the number of friends they have that you don't know", type "One" is "refer friends based on the number of friends you have that don't know them" and type "Both" means type "One" and "Two".
