_OperationsList is a Sequence containing FeatureOperations. The FeatureOperation can be accessed via square brackets using an index (to get the i-th operation) or using a string representing the column name (to get all the operations related to that column).
It can be iterated over and is possible to get the derived columns from a column or to get the original columns that generated a column.
An instance of _OperationsList will be contained in a Dataset to keep track of the preprocessing steps on that Dataset [implementation in a successive PR]
