Trac #13627: implemented xgcd for padics
bernoulli distributions
first discrete gaussian sampler implemented
slow uniform+online implementation of discrete gaussians added
first version of mp versions of discrete gausians done
added double precision variants, but these are not much faster
added ZZ.random_element(gaussian) and fixed LWE to use new sampler
added parameter c for discrete Gaussians
discrete gaussians (mp version) support arbitrary c now
more careful considerations of tau + documentation
fixed precision='dp'
documentation clarification
Merge branch 'develop' of trac.sagemath.org:sage into discrete_gaussian

DDLL23 -> DDLL13
remove superfluous __call__ funcs
fix typo
