Lazy loading support

[yesazo]

Currently setRows() iterates through the whole collection. Is it planed to support a kind of lazy collection (e.g. like Viritin MGrid).

That's a good suggestion, I will keep that in the backlog. Currently my time is quite limited so I am only bug fixing, but my plan is to continue active development (based on user suggestions, like that one) on some point later on.
