#========EX5==========
#NOW WE WANT PLAYERS TO ENTER THE NAME OF THE LOCATIOn, not a direction
#so you can just type 'valley' and go there
#so we add road, hill etc to the vocabulary
"""So we can't store the directions in Vocabulary. Instead, we store the location numbers, then map them 
to the appropriate location.
From the Valley, typing Road should go north, so the vocabulary maps "ROAD" to "1" 
and in the exits entry for Valley we map "1" to location 1.
Typing Hill from the Valley needs to take you West, so we map "HILL" to "2", then in the Valley's exits entry 
we map "2" to location 2 (which is the hill)."""
