Allow easier definition of property configurers (ie in the Assembly)

[jasperblues]

Typhoon supports property configurers. The current way to define them is:

TyphoonComponentFactory* factory = [TyphoonBlockComponentFactory factoryWithAssembly:[ApplicationAssembly assembly]];

id <TyphoonResource> configurationProperties = [TyphoonBundleResource withName:@"Configuration.properties"];
[factory attachMutator:[TyphoonPropertyPlaceholderConfigurer configurerWithResource:configurationProperties]];

It might be nice to allow definition of configurers in the Assembly (code or xml).

This would be convenient. As a proposition even further, could it be a good idea to introduce the concept of infrastructure components?

A component recognised and picked-up by the factory but not included in the registry. The TyphoonPropertyPlaceHolderConfigurer being a good example, that if defined in the assembly automatically being attached as a mutator before component definitions are processed.

Opens up for adding other infrastructure components later, AOP components for example if that is in the road map.

I've put together a draft implementation for it here:

Hi Erik,

That would be exactly right. Perfect.

(I couldn't find the draft spec - link takes me to main page. . but get the gist).
