All this is *way* more complicated than what I have time for now. I am planning 
to create auxilliary tff (text feature file) files for each text file given as 
input (either on the command line or from a file). These will contain (TermID, 
term frequency) pairs, which will be read by a modified version of 
extract_features after extracting the image features (the convention being that 
we have ImageName.jpg (or gif or whatever) accompanied by ImageName.txt, 
leading to ImageName.tff. The result will be fts files which the inverted file 
generator should be able to slurp in unmodified - we will just now have another 
feature group. Conseqently the text and image index should look just like a 
"normal" gift index.

I realise that this is extremely quick and dirty, but I have a student waiting 
on it who has a tight deadline for the submission if her minor thesis. 
Hopefully I will be able to integrate this into the full framework later.
