TYPICAL OBJECTS OF TYPE Quotable Group

</defs>

This type represents a family of Quotable objects defined analogously to the mathermatical concept of the "equivalence class" through the following construction mechanism:

Given a specific Deriscope Object of type Quotable plus the definition of some so-called "equivalence relationship", then the family here represents the set of all Quotable objects that are "equivalent" to the given object in accordance with the specified "equivalence relationship.

A simple example of such a construction is the "Discount Quotable Curve", which can be derived from a specific Discount Quotable object (eg a USD matured in 10 Mar 2020") together with the "equivalence relationship" that stipulates that any two Discount Quotable objects with the same currency are deemed to be "equivalent".
The resulting "Discount Quotable Curve" can thus be seen to model the whole set of Discount Quotables wrt a given currency regardless of their maturity.
It is natural to identify this concept with a "Discount Quotable Curve" whose value at any time is a mathematival one-dimensional curve.
