Detailed Description
template<class TIterator, class BoolFunctor>
class til::ConditionalIterator< TIterator, BoolFunctor >
Conditional iterator for images.
As opposed to a standard iterator, a conditional iterator takes a boolean functor as a parameter, and will iteratate for those elements that returns true. The ConditionalIterator class actually contains only this mechanism; all the iterator mechanism itself should be provided by an iterator from which ConditionalIterator derives, and which is a parameter of templation. So ConditionalIterator just provides this functionality to already existing iterators. Example: itlin(im, _1 >0) provides a linear iterator for image im for voxels that are strictly positive.

Go to the next element if possible.
Note that with conditional iterators the concept of a for loop, with increase and test at a different place, is awkward.
