getSuggestions without max_count argument

[wouterbeek]

Function getSuggestions is very nice since it implements the following two common use cases:

1. Auto-completion for typing IRIs and literals
2. IRI namespace matching

Currently a maximum size must be given to the function, but this maximum is not always known beforehand. For example, if you want to find all DOI IRIs (use case category 2), there are over 4M matches for prefix http://dx.doi.org/ in LOD-a-lot.

Would it be possible to return the list of suggestions as an iterator of lazy list of arbitrary size?

I have implemented an iterator for getSuggestions in develop, commit d7e93d1

See an example of use in: tests/getSuggestions

Let me know if this solves this issue.
