- Update the biostDemo vignette.

- Fix the show method for offsets "out of bound".

- We still have the following problem:

    pattern <- DNAString("CAG")
    
    subject <- DNAString("GTTCA")
    subject@offsets
    matches <- matchDNAPattern(pattern, subject, mis=2)
    matches@offsets
    matches
    
    multi <- DNAString(c("TTTTT", "GTTCA", "TT"))
    multi@offsets
    
    subject <- multi[2]
    subject@offsets
    
    matches <- matchDNAPattern(pattern, subject, mis=2)
    matches@offsets
    matches
