Changes for R-package Lumninescence

Version 0.1.7 (May 24th, 2012)
	- Analyse_SAR.OSLdata(): correct error for cases in that a cutheat was not applied as TL
	- Calc_OSLLxTxRatio(): correct consistency check for Tx.data producing warnings
	- Analyse_SAR.OSLdata(): correct function call, causing unexpected behavior 
	- plot_Histogram(): unify xlab behaviour
	- plot_Histogram(): error correction causes by different column selection
	- plot_GrowthCurve(): Add D0 value as output in De list element
	- plot_GrowthCurve(): Correction - remove third digit for De value and minor error correction
	- plot_DeDistribution(): Minor correction for the graphical output
	- fit_LMCurve(): Update examples
	- ExampleData.FittingLM: Replace sample and update sample information

Version 0.1.6 (April 27th, 2012)
	- add function: Calc_FuchsLang2001()
	- add function: Calc_FadingCorr()
	- fit_LMCurve(): minor error correction for pLM data, log axis was shown for linear scale
	- fit_LMCurve(): add logical argument fit.calcError for error estimation
	- fit_LMCurve(): add argument bg.subtraction for different methods of bg subtraction 
	- fit_LMCurve(): change - the function now returns a list instead the nls() object (see manual)
	- fit_LMCurve(): minor error handling improvements 
	- plot_BINfileData(): minor error correction for lab unit - insert round() for unit
	- plot_BINfileData(): remove non-ascii character for degree celsius for compatibility to windows
	- plot_BINfileData(): add option SET for argument sorter
	- plot_GrowthCurve(): remove parameter c from EXP+EXP function to improve fitting stability
	- Analyse_SAR.OSLdata(): remove non-ascii character for degree celsius for compatibility to windows
	- plot_DeDistribution(): xlab now requires the full characters
	- plot_RadialPlot(): introduce argument zlab instead of xlab.unit 
	- plot_RadialPlot(): replace argument logDe by zscale.log
	- plot_RadialPlot(): correct text for central value using the log scale option
	- plot_RadialPlot(): further minor improvements suggested by Rex Galbraith

Version 0.1.5 (Apr 08th, 2012)
	- add function: plot_RadialPlot()
	- add function: Analyse_SAR.OSLdata()
	- add function: Calc_OSLLxTxRatio()
	- add dataset: ExampleData.LxTxOSLData
	- extent show method for Risoe.BINfileData by position, run and set data
	- plot_DeDistribtion(): add option for plotting distribution parameters like mean or median (suggested by Margret Fuchs)
	- fit_GrowthCurve(): add fitting with weights as suggested by Michael Dietze and Margret Fuchs
	- fit_LMCurve(): add option fit.advance using a stochastic process for start parameter recognition
	- fit_LMCurve(): correct an error: in a few cases the fitting failed but no pseudo sum function was shown
	- fit_LMCurve(): correct an error in the automatic start parameter finding routine which results in NA values
	- fit_LMCurve(): correct y-scaling for log-x plot using pLM data

Version 0.1.4 (Mar 01th, 2012)
	- add function plot_BINfiledata() with example data
	- add function plot_GrowthCurve() with example data
	- add example data for plot_GrowthCurve()
	- add function CW2pLM() with example
	- fit_LMCurve(): add option for pLM data in fit_LMCurve
	- fit_LMCurve(): legend adjustment for pLM curve plot
	- fit_LMCurve(): supress error messages for try-errors 
	- readBIN2R(): now returns an S4 object with two slots
	- add Risoe.BINfileData-class 
	- add show method for Risoe.BINfileData-class
		
Version 0.1.3 (Feb 10th, 2012)
	- error corrections on the man files
	- fit_LMCurve function now returns a nls object
