Complete generation of abstract in php

class X
{
abstract;
}

Or,

abstract class X
{

}

The first syntax is suggested even though it is against the convention in other languages.
We already can declare a class as 'singleton'.

Doing this would require also changing UmpleOnline to allow marking a class as abstract.
There are metamodel and code generation implications.

I'm looking into this currently. My plan is to go for the first method for the Umple
syntax. That way it follows how "singleton" and "immutable" are done. Consistency
is important I think here.

The abstract keyword is in place and working correctly. Simply doing the following:

class Student
{
abstract;
}

Will make the class "student" an abstract class such that if you were to generate Java
code the class would be "public abstract Student".

The only thing left right now is two fold, as I see it:

1. This only works for Java code generation currently, other languages will need the
   implementation which should be a jet-template change (the jumpjet)

2. Checks to ensure instantiation of an abstract class are impossible. It was mentioned
   by Andrew that this would be solved if the native language compilers (javac for Java,
   or gcc for C++) would bubble up the errors.

If time permits I will have this solved before the end of term (next week), if not
I'll simply solve it afterwards as I'm more than comfortable continuing onwards.
