Query: On one-point extensions of cluster-tilted algebras   We define an operation which associates to a pair (B,M) where B is a
cluster-tilted algebra and M is a B-module which lies in a local slice of B, a
new cluster-tilted algebra B'. In terms of the quivers, this operation
corresponds to adding one vertex (and arrows).
