Calculate the cue validity for a pair of vectors. It is calculated as correct / (correct + incorrect).

1	cueValidity(criterion, cue, replaceNanWith = 0.5)

`criterion`	A vector of values to be predicted.
`cue`	A vector of values to predict with. Should have the same length as the criterion.
`replaceNanWith`	The value to return as cue validity in case it cannot be calculated, e.g. no variance in the values.

The cue validity, a value in the range [0,1].

cueValidityComplete for more complete output.

conditionalCueValidityComplete for a version where validity is conditional on cues already used to make decisions.

cueAccuracy for a measure that takes guesses into account.

cueValidity(c(5,1), c(1,0))
# Returns 1.
cueValidity(c(5,2,1), c(1,0,0))
# Also returns 1
cueValidity(c(5,2,1), c(0,0,1))
# Returns 0.
cueValidity(c(5,2,1), c(1,0,1))
# Returns 0.5.
