 Modified Black Body module
 ======================================
 
-This module implements a modified black body (MBB). This MMB can be 
-a stand-alone IR emission or it can come as an additional component. 
-The energy balance can be set to check the presence of a component 
-or not to account for the emission of a region completely embedded 
-in dust and not visible in the wavelength range.
