### News and Bugs fixed in CalcHP

(08.12.2018) Release 3.7.4
1) Form output. Bugs fixed : symb/out/form_out.c

2) Detection of duplicate names in var#.mdl and func#.mdl. Bug is fixed : symb/read_mdl.c

3) Decay branching is sorted now.

4) aPrintF works correctly even if "long double" or "_Quad" is chosen for real numbers.
aPrintF routine is intended to write input file for spectrum calculator from within
func#.mld. It is similar to fprintf function and its first arguments defines format of
reading of other arguments.
For real argument one of flags E,e,G,g,f,F has to be used, which corresponds to double
numerical type.
Now when CalCHEP performs numerical calculations with other types, earch real argument
of aPrintF is automatically
converted to type double: X => (double)(X). : symb/out/reader_c.c

5) Polarization of incoming photon in case when second incoming particle is
massive. Bug is fixed:
symb/symbolic.c

6) External matrix element.
We have realized a possibility to use CalcHEP numerical integrator with
external matrix element.
We assume that the uses has compiled some processes in CalCHEP but would
like to replace CalcHEP squared matrix
element on his own one. See instructions in
c_source/num/usrSQME_dummy.c
