Elimination of the limit concerning the number of heating emitters in series per ring

As of the 2015.h version, CYPECAD MEP designs heating installations with heating emitters in series (single-tube system) without limiting the number of emitters in the ring. This way, users will determine the viability of the single-tube heating installation based on the warnings and results provided by the program without limiting the number of emitters to a maximum number of 5 per ring as was done in previous versions.
