libvb/Constellation: make dessinification optional
libvb/Constellation: option for slow drawing (very slow!)
Upgrade WAF to version 1.8.4
OK so the bug with gcc49 was my fault
libvb/Hypermap_lib: two more maps
libvb/Constellation: default arguments go in the implementation
libvb/Constellation: remove two more warnings
libvb/Constellation: we can trust a few more digits in higher precision
tests/test_hypermap: pause before quitting if asked
libvb/Constellation: use proper complex coordinates in the drawing
libvb/Constellation: compute the cost as a vector for sharing later
libvb/Constellation: factorize the constructor a little
libvb/LinearAlgebra: declare matrices and vectors, compute det and inverse
libvb/Constellation: compute the jacobian and check it
libvb/Constellation: use the jacobian - code is getting much neater!
libvb/Constellation: compactify the code a bit
libvb/Constellation: get rid of gradcost() and friends
libvb/Constellation: building vectors to use coovec was a bit redundant
libvb/Constellation: vec is a complex-valued variant to coovec
libvb/Constellation: it is much better to call readcoo explicitly
