Creates a NotEmptyList starting with a head and containing all the elements of the optional tail.

Calling from Kotlin

Here's an example of calling this function from Kotlin code:

val integers: NotEmptyList<Int> = NotEmptyList.of(1, 2, 3)
assertEquals(expected = "[1, 2, 3]", actual = "$integers")

The NotEmptyList type being an inline value class, this function is not available yet for Java users.
