Jaccard similarity between logical vectors

Jaccard similarity between logical or 0-1 vectors: sum(c1 & c2)/sum(c1 | c2).

clujaccard(c1,c2,zerobyzero=NA)

`c1`	logical or 0-1-vector.
`c2`	logical or 0-1-vector (same length).
`zerobyzero`	result if `sum(c1 \| c2)=0`.

Numeric between 0 and 1.

c1 <- rep(TRUE,10)
  c2 <- c(FALSE,rep(TRUE,9))
  clujaccard(c1,c2)
