/**
 * An <code>AnyVal</code> for non-zero <code>Long</code>s.
 *
 * Note: a <code>NonZeroLong</code> may not equal 0.
 *
 * <p>
 * Because <code>NonZeroLong</code> is an <code>AnyVal</code> it
 * will usually be as efficient as an <code>Long</code>, being
 * boxed only when an <code>Long</code> would have been boxed.
 * </p>
 *
 * <p>
 * The <code>NonZeroLong.apply</code> factory method is implemented
 * in terms of a macro that checks literals for validity at
 * compile time. Calling <code>NonZeroLong.apply</code> with a
 * literal <code>Long</code> value will either produce a valid
 * <code>NonZeroLong</code> instance at run time or an error at
 * compile time. Here's an example:
 * </p>
 *
 * <pre class="stREPL">
 * scala&gt; import anyvals._
 * import anyvals._
 *
 * scala&gt; NonZeroLong(42)
 * res0: org.scalactic.anyvals.NonZeroLong = NonZeroLong(42)
 *
 * scala&gt; NonZeroLong(0)
 * &lt;console&gt;:14: error: NonZeroLong.apply can only be invoked on a non-zero (i != 0L) integer literal, like NonZeroLong(42).
 *               NonZeroLong(0)
 *                      ^
 * </pre>
 *
 * <p>
 * <code>NonZeroLong.apply</code> cannot be used if the value being
 * passed is a variable (<em>i.e.</em>, not a literal), because
 * the macro cannot determine the validity of variables at
 * compile time (just literals). If you try to pass a variable
 * to <code>NonZeroLong.apply</code>, you'll get a compiler error
 * that suggests you use a different factor method,
 * <code>NonZeroLong.from</code>, instead:
 * </p>
 *
 * <pre class="stREPL">
 * scala&gt; val x = 42L
 * x: Long = 42
 *
 * scala&gt; NonZeroLong(x)
 * &lt;console&gt;:15: error: NonZeroLong.apply can only be invoked on an long literal, like NonZeroLong(42). Please use NonZeroLong.from instead.
 *               NonZeroLong(x)
 *                      ^
 * </pre>
 *
 * <p>
 * The <code>NonZeroLong.from</code> factory method will inspect the
 * value at runtime and return an
 * <code>Option[NonZeroLong]</code>. If the value is valid,
 * <code>NonZeroLong.from</code> will return a
 * <code>Some[NonZeroLong]</code>, else it will return a
 * <code>None</code>.  Here's an example:
 * </p>
 *
 * <pre class="stREPL">
 * scala&gt; NonZeroLong.from(x)
 * res3: Option[org.scalactic.anyvals.NonZeroLong] = Some(NonZeroLong(42))
 *
 * scala&gt; val y = 0L
 * y: Long = 0
 *
 * scala&gt; NonZeroLong.from(y)
 * res4: Option[org.scalactic.anyvals.NonZeroLong] = None
 * </pre>
 *
 * <p>
 * The <code>NonZeroLong.apply</code> factory method is marked
 * implicit, so that you can pass literal <code>Long</code>s
 * into methods that require <code>NonZeroLong</code>, and get the
 * same compile-time checking you get when calling
 * <code>NonZeroLong.apply</code> explicitly. Here's an example:
 * </p>
 *
 * <pre class="stREPL">
 * scala&gt; def invert(pos: NonZeroLong): Long = Long.MaxValue - pos
 * invert: (pos: org.scalactic.anyvals.NonZeroLong)Long
 *
 * scala&gt; invert(1L)
 * res5: Long = 9223372036854775806
 *
 * scala&gt; invert(Long.MaxValue)
 * res6: Long = 0
 *
 * scala&gt; invert(0L)
 * &lt;console&gt;:15: error: NonZeroLong.apply can only be invoked on a non-zero (i != 0L) integer literal, like NonZeroLong(42L).
 *               invert(0L)
 *                      ^
 *
 * </pre>
 *
 * <p>
 * This example also demonstrates that the <code>NonZeroLong</code>
 * companion object also defines implicit widening conversions
 * when either no loss of precision will occur or a similar
 * conversion is provided in Scala. (For example, the implicit
 * conversion from <code>Long</code> to </code>Double</code> in
 * Scala can lose precision.) This makes it convenient to use a
 * <code>NonZeroLong</code> where a <code>Long</code> or wider type
 * is needed. An example is the subtraction in the body of the
 * <code>invert</code> method defined above, <code>Long.MaxValue
 * - pos</code>. Although <code>Long.MaxValue</code> is a
 * <code>Long</code>, which has no <code>-</code> method that
 * takes a <code>NonZeroLong</code> (the type of <code>pos</code>),
 * you can still subtract <code>pos</code>, because the
 * <code>NonZeroLong</code> will be implicitly widened to
 * <code>Long</code>.
 * </p>
 *
 * @param value The <code>Long</code> value underlying this <code>NonZeroLong</code>.
