/**
File creation facility interface.

An abstract class for all extensions that are responsible for file creation.

Instances that implement this interface are available through extension architecture:
@code
KDevCreateFile *cf = extension<KDevCreateFile>("KDevelop/CreateFile");
if (cf) {
    // do something
} else {
    // fail
}
@endcode
