Detailed Description

template<class T>
class Fiber::CreativeIterator< T >

An iterator with an optional DataCreator, which is just a class to intercept creation of data along a subset.

The overhead of using a data creator is small if there is none, as it is just checking for its existence here. If a data creator is specified, then there will be a virtual function call overhead, which however is still fast as compared to what the data creator will actually do.
