Re: Cello: a library of string algoritms using succinct data structures

@Krux02 I could just use a concept and be done. BUT it turns out I actually 
need to know that I am working with data from disk, because in this case I want 
to use disk-based sequences also for the intermediate data structures that I 
use in the constructions - something that I am not doing right now but I plan 
to support.
