Added algorithm for adjusting the size of cells. It is very important in the case of duty tables (as in the Ray's case). Now all problems from the Ray's course with even ugly tables can be printed more or less reasonably. I am working on the implementation of the user defined length of cells <td width="...">. It'l' be finished soon.
