Small improvements in the Rythm template sample in README.md

[greenlaw110]

The following template segment:

@if (person.getName() != null) {
   Hello @person.getName()!
}

could be written as:

@if (person.getName()) {
   Hello @person.getName()!
}

So @if in Rythm is smart enough to deal with null value. see http://rythmengine.org/doc/directive.md#if for more information.

or it can be even simplifed as

Hello @(person.getName() ?: "new user")

It means if person.getName() is null, then "new user" is output, otherwise the name of the person is output in place

Another place could be simplified:

@args String who
@args String what
@args String why

version 1:

@args String who, String what, String why

version 2:

@args() {
String who
String what
String why
}

Thanks for the input! I'll update the example as you've suggested. It certainly helps with the brevity of the app (which was one of the goals).

Sorry for the late reply, the github notification got lost in my in box and I haven't had time to come back to this project. I'm hoping to get back into it soon and start fleshing things out!
