Move simulations to ...

[jarlebring]

Move simulations to http://www.github.com/matrixfunctions/GraphMatFunData with the following directory structure

src
src/generated/  
src/generated/graphs
src/generated/matlab
src/generated/julia
src/generated/c
src/scripts  
src/scripts/generate # Contains scripts to create files in src/generated either from /data or with graph_XX_ functions
src/scripts/opt  # optimization routines to create data files
data/   # all the cgr files
data/exp
data/sqrt

Note that we want the generated code to be inside the repo.

Which of the graphs do we want to take from this repo? Only the graphs in "newgraphs", or also the ones in "graphs"?
Do we want to remove the things on the "old" directory and rename things to not be called "new"?

newgraphs only. I would also like to check that the newgraphs are also the best. The GraphMatFunData should be selfcontained and there is no need to call it new. Eventually we should remove the simulations directory.
