Detailed Description

Combines multiple PartitionFunction instances into a single composite strategy.

Maintains an ordered list of sub-functions and delegates evaluation and derivative calls to the first function that supports the requested isotope.

See partition_composite.cpp for details on sub-function selection and error logging.

Exceptions

std::runtime_error

If no sub-function supports a given (z,a,T9) in evaluate or evaluateDerivative.
