npm install pyxis1) Associative: values are referenced by key and not by position.
2) Unique keys: each key in container is unique.
3) Ordered: all keys are kept in order.
4) Mapped: each entry associates a key to a mapped value.
1) empty : test whether container is empty or not.
2) clear : empties container
3) size : returns number of entries in container.
4) locate(key) : locates value of entry by key.
5) insert(key, value) : inserts a unique key into container in sorted order.
6) remove(key) : removes key and its associated value from the container.
7) enum : enumerate the keys in the container
