Merge branch 'master' of ssh1.it-sudparis.eu:~granger/dev/liblooklike

This merge does nothing
working algorithm as for precision, some bugs still break execution on some examples
removed some debug print, precision issue on biggest eigen value computation breaks programs execution
WIP
precision problem solved by using the trace of the matrix and thus skipping computation of the last eigen value
Eigens of a bidimensional matrix
normalisation
Change on |dm-dk| for second deflation
wip
resolved merge
isolated pcomputation problems as the conditions on the deflation
wip
