h1. Sequence: generate auto increment ID

Start from v1.2.11, PlayMorphia provides a @Seq@ class to generate auto increment ID with easy to use interface:

bc. long myId = Seq.nextValue(); // generate auto increment value on a global namespace
...
myId = Seq.nextValue("foo"); // generate auto incremental value on "foo"
...
myId = Seq.nextValue(Bar.class); // generate auto incremental value on Bar class
...
Seq seq = Seq.next();
// print sequence value prefixed with "ABC" and with 6 digits, padding with leading 0s
System.out.println(seq.getAsString("ABC", 6));
