Sensible & latent heat API

Computes sensible heat Q = m·cp·ΔT for a temperature change and latent heat Q = m·L for a phase change (with optional phase fraction), returning the total — the classic don't-forget-the-latent-term energy balance. Answers 'How much energy to heat and boil this water?', 'What is the total heat for a phase change?'.
