I am an interpreter for export recipes. ## Recipe format Recipe is an array, which can contain two kinds of elements: - an assocation where the key is the receiver and the value is a two-arguments selector In this case, `receiver perform: selector withArguments: { data. stream }` is called. This essentially defines one step of export process. The key (eg. receiver) is presumed to be some kind of 'repository' of the exporting methods that just format appropriate aspect of data into a stream; like a class or a singleton, so that the recipe itself can be decoupled from data. - a subarray, where first element is special and the rest is recursive recipe. `subarray first` must be an association similar to one above, with key being the 'repository' receiver, but value is one-arg selector. In this case, `receiver perform: selector withArguments: { data }` should create a collection.
