FIBOFTF2 — Augment the Analytics ontology (originally from FIBO IND) with Expression, Formula, and Variable

Additional classes and properties are needed to support FIBO SEC/Securities and dependent derivatives ontologies. These include basic Expression, Formula, and Variable classes, as well as properties such as hasArgument, hasExpression, and hasFormula, originally part of the "out of scope" material from the semantics repository ontologies in the Math module. The target set of concepts should include exactly those concepts and relationships required for SEC/Securities, SEC/Debt, and and SEC/Equities, as well as to support DER/DerivativesContracts, but no unnecessary material.

Changes in Analytics for JIRA issue 23

The original Analytics ontology included with the FIBO IND specification included classes describing measures and statistical measures. This issue merges that ontology into the main FIBO FND Specification and augments the ontology to provide additional features needed in for Business Entities, Indices and Indicators, Securities, and additional ontologies to be integrated into the FIBO family of specifications over time. Some of the properties of the original Analytics classes referenced dates, such as applicable start and end dates, calendar years for which the measures are appropriate, and so forth. These need to be revised to reference the new FND FinancialDates ontology for more accurate and complete definition. In addition, several new classes and properties for Expression, Formula, and Variable are required to support the forthcoming SEC/Securities specification.
