Clarify ambiguous printout in internals function
Clarify the role of prior bounds in the manual
Cosmetic changes

- Suppresses spurious output from dynare_estimation_1.m
- Removes unset output argument from dynare_estimation_init.m (which seems to be totally unused as it was not set at all and nobody reported any crashes)
- Corrects header of dynare_estimation_init.m

Cosmetic changes
Fixed typo (wrong condition for defining the integration weights and nodes).
Correction on PR #734 (role of prior bounds).
Correction of PR #734 (model comparison).
Merge branch 'bound_documentation'
Fix bug in in CutSample.m that led to wrong number of draws for moment computation (first part of PR #733)

FirstLine actually defined the last line. One needs to 1. Otherwise,
Draws in GetAllPosteriorDraws.m will be (NumberOfDraws+1)*nblck.
Fixes ambiguity in the output of CutSample routine (second part of PR #733).
Merge branch 'cut_sample'
Reflects Michel's comment on aa503abfa79145efc0840c79210e795e1b76df84.
Cosmetic changes in headers
Make sure the output arguments of dsge_likelihood.m are actually set

Before, trend_coeff and ys were sometimes returned as empty
Document Univariate Kalman Filter
Deal with NaN and Inf in Hessian of dynamic model

Checks for these cases in stochastic_solvers.m to prevent cryptic crashes in dll-files later on
Add check for NaN parameters to initial_estimation_checks.m

Provides important info to debug cryptic crashes in later routines. Mostly applies to cases where people run estimation without stoch_simul
