- Add FormulaEvaluator class with d4rt integration
- Support single output variable formulas with variable injection
- Include comprehensive error handling and validation
- Add 15 test cases covering evaluation scenarios
- Create working example with Newton's law, quadratic discriminant, etc.
- Export evaluator in main library file
Implements formula evaluation by injecting variable declarations
into d4rt source code, enabling execution of mathematical formulas
with input parameters.
- Add VariableSpec class with magnitude field validation
- Add Formula class supporting multiple input/output variables
- Support d4rt_code as string or object with code field
- Add comprehensive tests for parsing and serialization
