Modified: /trunk/ schedule.ccl /trunk/src/ Bin_NS.cc

Log: a few corrections (rho~=0 handling, shift fix), still unknown: correct curvature transformation -> bin_ns.h mentioned K^{ij} being exported, but Eric G. mentioned it is K_{ij}, which indeed results in lesser mom-constraint violation. However, both versions do not converge - unlike the ham constraint violation
