KeyIndex

KeyIndex is used to store the keys for the super::ColumnFrame The keys are stored in the order they are added - the order is preserved The keys are stored in the Vec and the indexes are stored in the HashMap The indexes are used to access the data in the super::ColumnFrame by the column Key NOTE: The keys are unique - if the key is already present, it will be removed
