Computes the cummulative sum of a vector without propagating NAs

1	cumsumNA(x)

`x`	An integer or double vector

If x is integer, then integer addition is used. Otherwise, floating point (double) addition is used. Elements in x that were NA will continue to be NA, but the NA will not be propagated.

The vector of cumulative sums.

cumsum

# Compare to cumsum()
x <- as.integer(c(5, 2, 7, 9, 0, -1))
cumsum(x)
cumsumNA(x)

# Now with missing values
x[c(2,4)] <- NA
print(x)
cumsum(x)
cumsumNA(x)
