load words on import... this might be controversial?  choose where you import this module wisely.
in findNeighbors, we only need to traverse the cell history once. do this at the start of the function not everytime we try to append. In walkTheSet second for loop removed the y_val var, it never gets used.  added the findLargerWords function to do the dictionary word search in the loop.  this will deconstruct the list as we go reducing memory footprint.
adding more tests for locate2d functions
