Improve display of posterior parameters and clarify use of HPD
nostrict command-line option ignores extraneous assignments in initval. closes #1
nostrict option works for endval too

Improve display of posterior parameters and clarify use of HPD
fixed bug with calibrated models in dyn_estimation_init.m introduced
in commit 952139b
Added methods in dynSeries class for filtering (hptrend and hpcycle).
Do not produce plot in dynSeries::hpcycle unitary test.
Added missing tag for triggering unitary tests.
Added Baxter and King (1999) band pass filter for dynSeries objects.
Added headers.
Fixed bug affecting fs2000/fs2000_calib.mod and shock_decomp_calibrated_model/example1_calib_shock_decomp.mod.
adding tests for shocks decomposition of estimated model. Closes #313
adding missing data file in previous commit
Added new routine to generate strings randomly.
Fixed bug manifesting if a model is first estimated with cova_compute=0 and if the resulting mode file is loaded after.

Added condition on the existence of hh in the mode_file.
Update Ferhat's affiliation
Add missing dash
Update Junior's affiliation
Removed useless routines for gradient evaluation (called by csminwell).
Changed logic in numgrad2.

Do not compute the left derivative if the evaluation of the objective function at x+h returns a non zero cost_flag (ie a problem with BK, steady state, ...).
