Define lazily evaluated test data via ```def()``` and ```subject()``` functions.

## Usage

### Without jasmine-def

```javascript
describe('old spec', function () {

  // order is important, options must be defined before subject
  beforeEach(function () {
    this.options = { foo: 'foo' };
  });

  beforeEach(function () {
    this.subject = new SomeObject(this.options)
  });

  it('works', function () {
    expect(this.options).toBeDefined();
    expect(this.subject).toBeDefined();
  });
});
```

### With jasmine-def

```javascript
describe('new shiny spec', function () {

  // order is not important, defined properties are lazy evaluated
  subject(function () {
    return new SomeObject(this.options)
  });

  def('options', function () {
    return { foo: 'foo' }
  });

  it('works', function () {
    expect(this.options).toBeDefined();
    expect(this.subject).toBeDefined();
  });
});
```
