/**
 * To make your benchmark depend on a parameterized value, create a field with the name you want
 * this parameter to be known by, and add this annotation. Caliper will inject a value for this
 * field to each instance it creates. These values come from
 *
 * <ul>
 * <li>The command line, if specified using {@code -Dname=value1,value2,value3}
 * <li>Otherwise, the {@link #value()} list given in the annotation
 * <li>Otherwise, Caliper looks for a static method named {@code paramName + "Values"} (for
 *     example, if the parameter field is {@code size}, it looks for {@code sizeValues()}). The
 *     method can return any subtype of {@link Iterable}. The contents of that iterable are used as
 *     the parameter values.
 * <li>Otherwise, Caliper repeats the previous check looking for a static <em>field</em> instead
 *     of a method.
 * <li>Otherwise, if the parameter type is either {@code boolean} or an {@code enum} type, Caliper
 *     assumes you want all possible values.
 * <li>Finally, if none of the above match, Caliper will display an error and exit.
 * </ul>
 *
 * <p>Caliper parameters are always strings, but can be converted to other types at the point of
 * injection. If the type of the field this annotation is applied to is not {@link String}, then the
 * type class must contain a static {@code fromString(String)}, {@code decode(String)} or {@code
 * valueOf(String)} method that returns that type, or a constructor accepting only a {@code String}.
 *
 * <p>Caliper will test every possible combination of parameter values for your benchmark. For
 * example, if you have two parameters, {@code -Dletter=a,b,c -Dnumber=1,2}, Caliper will construct
 * six independent "scenarios" and perform measurement for each one.
