Added octave code to repo

A new directory containing octave source code was added.
The Octave source only does 1 sweep from the top at the moment,
and will print everything to png's if asked. See README in the
octsrc folder

Also, an organizational change was made to the c code.
The makefile was modified so all the object files were
generated in their own directory rather than filling up
the base directory with crap.
new Multi-bulge octave code

The octave code now contains colAndBust.m.
It takes a hessenberg matrix and creates bulges passed to it,
then moves the bulges (of the same size with the same shifts)
towards the center until they meet.
Please note that the eigenvalues seem to shift a little... not good
fixed colAndBust

colAndBust now successfully pushes bulges together without
breaking anything

Furthermore, my email was corrected in the readme
merges bumps into 1
actually does as advertised

colAndBust not brings 2 bulges with distinct shifts
together and then busts it open.

hessen is a cheesy hessenberg reduction (output matches
octave's built in one) - for my crappy laptop
updated gitignore
ignore more pix
wrap function for deriv
Better sign function
fixed pix
Merge pull request #1 from solter/master

Here's octave shit
