!MadGraph5 Syntax For generate events

Compare to MG4 the syntax is basically the same but

   1. All particles should be separated with a spaces

      write this:
         w+ > ve e+
      and not:
         w+>vee+

   2. The coupling is specify after the process in the same line
      Please note that::
        a. Note that contrary to !MG4 the default for the coupling is to infinity
        b. couplings are case sensitive

      write this:
         w+ > ve e+ QED=2
      and not:
         w+>ve e+ qed=2

   3. you can still use the special tag at the end of the process
      a. "/" fordids the following particles to appear in the process
      b. "$"  fordids the following particles to appear in a S-Channel

   4. The syntax for decay chain is different.
      a. In !MG5 the production process is separated from the decay by a coma. 
      b. Each part can be restricted by couplings/ special tag restrictions

      write this:
         g g > t t~ QED=0 /a, (t > b W+, W+ > l+ vl), t~ >j j j QCD=0
      and not:
         g g > (t >b (W+ >l+vl))(t~> j j j)
