L1centrality 0.3.1

• print.L1centNB() can now handle a graph with a missing vertex name (i.e., V(g)$name == NULL). If vertex names are missing, the function automatically sets them to V1, V2, ..., and prints them.

• The type argument is set to 1 in the quantile() function inside the L1centLOC() and L1centEDGE() functions.
