X1128: Maybe Add
Write a method that takes a key and an associated value as
parameters, and will only add them as anew entry in the map
if the key is not already present in the map--it will not
overwrite existing entries.
The map you will use is stored in a field within the class, as
shown below.
Your method should return true if an entry was added, or
false if the provided key is already present in the map and
so the pair was not added.
