Started implementing the new method with provable qsd-ness properties.

This commit works up to building the KKT matrix.
On the way... changed cone module completely.
New version is working in principle, but seems to have a memory leak in MATLAB (command line version with robustSVM data is fine)
Fixed bug in setup code that caused a segfault. Runs now also in Matlab.
Solved 1 Million instances of each test problem. Accuracy set to 1e-5, max #IR steps to 10.
eps-delta regularization, best version to date

Solves 99.98% of least_squares, 100% of other problems

9 steps of IR when needed.
Fixed minor issues with timing module and build modes.
Changed back to conicProduct() instead of dot product for calculating mu and mu_aff
when determining the centering parameter.
Update README.md
Update README.md
Added ecosqp.m, a MATLAB interface to ECOS for solving QPs easily.
This interface transforms a given QP into an SOCP, solves it, and
returns the appropriate variables.

Fixed also a tiny bug in the timing system (prevents overflow).
Merged updated readme

Merge branch 'master' of https://github.com/ifa-ethz/ecos
Update README.md

Added L1/LP and QP example
Update README.md
testing push
fixed bug with NULL A. added python module with CVXOPT compatibility
fixed printing function
added crude readme for python
added an example from cvxopt (LP), fig7.2-3 in the cvx book
now properly quits when something wrong with setup.
