Accumulating of heat to substance

Information
The "HeatAccumulation" library class models heat accumulation in Physiolibrary. This class has one thermal connector with temperature and heat flow. Heat energy is accumulated inside the class, stored in the variable "relativeHeat". This value is relative to normal body temperature of 37 °C; a positive value therefore indicates an internal temperature above 37 °C, while a negative value indicates temperature below 37 °C. Of course the particular value of temperature depends on the mass and specific heat of the instance.
