This example is for testing the 'pathsOverlap' method.
This file is almost the same as puzzle2 -- 
except for the last word path 'puzzle3-word7.txt'.

The last word (COLLEGES) overlaps the previous word (BUTLER),
because the first letter (C) overlaps the T in BUTLER.
Both are at position col=1 row=2.
