Merge pull request #20 from steenpass/andreas

final changes before submission
formulate the result on the structure of the exceptional cases
introduce the notations C(p(X)) and R(p(X))
add GM.tex

This is the document we discussed with Gert-martin on 12/06/2013.
copy the changes in GM.tex back to realclassify_2.tex

The statement about the equivalences in the case J_10 is not included here.
copy realclassify_2.tex to realclassify_3.tex
divide the content between realclassify_2.tex and realclassify_3.tex

Between the abstract and the bilbiography, we now have
realclassify_2.tex + realclassify_3.tex = realclassify_{2,3}.tex as it was.

section on the structure of the equivalence classes
  --> realclassify_2.tex
all the rest
  --> realclassify_3.tex
remove sections already included in part 1 from realclassify_3.tex

removed sections are:
- splitting lemma
- factorization results
- algorithms for simple singularities
add section titles to realclassify_2.tex
chg: rewrite the section on P1, P2 and P3

based on suggestions be Gert-Martin
