new course : parallel 1

#####for parallel or other level course :
It will be possible to redirect towards an other page in the m3p2 cursus.
Or to write here some paragraphes separated by html from an other pages, I think.
Or write here a completely new parallel course

For the moment, please wait.

Ya es possible hacer
I can here :
- write a full "parallel 1 course" if required
- or add add a few word about a "course parallel 1" that is written somewhere in "pages/curriculum/..."
- or do nothing.

    Go
