I worry about the name and location of the function.

1. Why plop this on `$.fn` when it's creating nodes that aren't attached to the DOM? I think any time anyone using an API off the wrapped jQuery results object (e.g. `$(window).createNodes()` is going to actually work on that document and/or underneath that selector). Is that actually happening in this case?  If not, I propose sticking it under the library's return object (e.g. `jasmineFixture.createNodes`).

2. The name `createNodes` reinforces the same idea that it does something with "nodes" (which most people assume to be on the DOM by default) that affix doesn't. Since it's working with nodes to the same extent as `affix`, I think the `Nodes` is unnecessary. 

How about we just name it `jasmineFixture.create()`? At some point I'm probably going to readdress the plugin to `jasmine.fixture.*` and it'll look nice to have `jasmine.fixture.create` and `jasmine.fixture.affix` next to one another.
