Detailed Description

Shared return types and arithmetic helpers for the templated Age of Information port.

The MATLAB AoI family in matlab/src/api/aoi/ returns one of two triples: [meanAoI, varAoI, peakAoI] for the fully parameterized queues (M/M/1, M/D/1, D/M/1) and [meanAoI, lstAoI, peakAoI] for the ones taking a Laplace-Stieltjes transform as input (M/GI/1, GI/M/1). Both live here, mirroring jline.api.aoi.AoiResult and jline.api.aoi.AoiLstResult; each ported function lives in its own header named after the MATLAB file, as required by the port convention.

An LST is represented as a std::function<T(const T&)> rather than a distribution object, exactly as MATLAB represents it as a function handle and the JAR as a LstFunction. Nothing in the family inverts an LST: the transforms are evaluated at real arguments only, and where MATLAB needs a derivative it takes a central difference with a fixed step.
