Failed at giving things a structure in tt. I need to put the src pointers into
t->*->values[i]... That way I could find all the related objects when I need
them.
moving things into the right way; the t->*->values approach seems to hold
dict.c: improve code style (I don't like &x[y])
tt.c,h: improve tt_output and tt_interpret to an almost working state
