	* Bugfixes for Para_deriv and Para_opt

Version 1.5.9 (2015-05)
	* outer and inner niche limits set to gradient range for all models for consistency

Version 1.5.8 (2015-04)
	* Para_opt and plot.HOF: corrected for M != 1
	* CRAN policy maintenance

Version 1.5.4 (Oct 11 2014)

	* Para.HOF: improvements

Version 1.5.3 (Oct 11 2014)

Version 1.5 (Sept 27 2014)
	* Para.HOF: Calculation of optima fixed
	* pick.model: Bootselect messages mechanism changed

Version 1.4 (April 22 2014)
	* HOF.default: missing test=test in pick.model subfunction prohibited other selection criteria than AICc during bootstrap

Version 1.3 (Dec 15 2013)
	* HOF.model: The backup procedure for optimization with function optim did not scaled the x gradient (to values between 0 and 1) and therefore gave wrong results
