This method calculates the Balaban J index.

1	balabanJ(g, dist = NULL)

`g`	a graph as a graphNEL object.
`dist`	the distance matrix of the graph. If the parameter is empty the distance matrix will be calculated within the function.

This method calculates the Balaban J index.

It returns the Balaban J index.
