applyValues -- apply a function to each value

applyValues -- apply a function to each value

applyValues(x,f) -- applies f to each value v in the hash table x to produce a new hash table.

Thus f should be a function of one variable v which returns a new value v' for the key k in the resulting hash table.

i1 : x = new HashTable from {a => 1, b => 2, c => 3}



o1 = HashTable{a => 1}

               b => 2

               c => 3



o1 : HashTable

i2 : applyValues(x, v -> v + 100)



o2 = HashTable{a => 101}

               b => 102

               c => 103



o2 : HashTable
