Calculate expectation of Truncated Normal distributions

1 2	etn(.mean = rep(0, 1), .sd = rep(1, length(.mean)), .low = rep(-Inf, length(.mean)), .high = rep(Inf, length(.mean)), .checks = TRUE)

`.mean`	Length K vector with the means of the K Normal distributions prior to truncation
`.sd`	Length K vector with the standard deviations of the K Normal distributions prior to truncation
`.low`	Length K vector with the lower truncation bound of the K Normal distributions prior to truncation
`.high`	Length K vector with the upper truncation bound of the K Normal distributions prior to truncation
`.checks`	Length 1 logical vector indicating whether to perform checks (safer) or not (faster) on the input parameters

The special values of -Inf and Inf are valid values in the .low and .high arguments, respectively.

A length K vector of expectations corresponding to the Truncated Normal distributions. NAs are returned (with a warning) for invalid parameter values.
