This class represents an operation performed to construct a DataTable.
An operation can have zero or more inputs. Operations with
no inputs are typically sources, those with one input perform some
form of transformation of the data, and those with more than one input
join or add data. The tree structure can be
traversed by using the Inputs property.
TryGetOutputSignatures(IReadOnlyListDataColumnSignature) can be used to check the output of the operation.
