Documention for How to change to compiling with debug options

[jgipsl]

To be done in section How to on the wiki.
Make sure that the following information is represented on the wiki (text coming from previous version of coding guidelines)

Don't stick to one compiler, no compiler will catch all your bugs. 
Always use multiple compilers to check, including all the error flags. 
For example, first compile locally with 
"gfortran -c -cpp -O0 -pg -g -Wall -ffpe-trap=invalid,zero -fbacktrace 
-fcheck=all -fbounds-check -pedantic". 

Then compile on asterix (if you’re at LSCE) with 
"ifort -c -cpp -g -O0 -debug -fpe0 -ftrapuv –traceback -check
arg_temp_created,bounds,format,output_conversion,pointers,stack,uninit". 

If you have an account, go on curie too, since they have the NAG compiler 
there which is good with error checking. 

Finally, running the code through valgrind will catch every single piece of 
memory that you use without initializing it (apart from some extreme cases), 
more thoroughly than a compiler. 
"valgrind -v --track-origins=yes ../../../bin/orchidee_ol". 
This is very slow, but a nice check.

Idea from Josefine: Ca serait bien de faire un page how to, pas forcement avec les mems infos mais pour activer le compilation avec des options de debug. Il faudrait mettre comment activer les options de debugage predefini (en mettant -debug au lieu de -prod) dans le makefile principale.

Also, rewrite the page Documentation/UserGuide/flag
