SF: revise manual of PetscSFGetGraph

close #999

Reported-by: Eric Chamberland (@eric.chamberland)

Add VecMean() to calculate arithmetic mean of the elements of a vector.

This is just a convenience wrapper around VecSum(), but having it is consistent with having MatGetColumnMeans().

Style: replace "!rank" with "rank == 0"

In SF tutorial ex1 (src/vec/is/sf/tutorials/ex1.c), add parentheses around "rank == 0". This is relevant because ! binds more tightly than +, but == binds les

Style: replace "!rank" with "rank == 0"

In SF tutorial ex1 (src/vec/is/sf/tutorials/ex1.c), add parentheses around "rank == 0". This is relevant because ! binds more tightly than +, but == binds less
tightly, so the result of the computation would otherwise change.
