Helper function for computing the log of difference

1	lnDiffErfs(x1, x2)

`x1`	argument of the positive erf
`x2`	argument of the negative erf

v <- lnDiffErfs(x1, x2) computes the log of the difference of two erfs in a numerically stable manner.

`v`	list(c(log(abs(erf(x1) - erf(x2))), sign(erf(x1) - erf(x2))))

1	lnDiffErfs(100, 10)
