- Added a little documentation of the sample data in inst/doc.

- Added the possibility to show standard deviation or confidence
  interval for the mean of the control values, if present in 
  the dose-response data. Also, control data (with dose=0)
  are not listed in the results data frame of drfit any more.

+This sample data is provided to show how dose-response data can be collected
+with a spreadsheet program like OpenOfficeCalc (sampledata.ods) or 
+MS Excel (sampledata.xls) and exported to CSV (comma separated values) format.
+OpenOfficeCalc 2.0 (German version, decimal separator is ',') produces
+sampledata.csv which can be read in by
+
+	>sampledata <- read.csv('sampledata.csv',skip=2,dec=',')
+
+and MS Excel 97 produces sampledata.csv2 which can be read in by
+
+	>sampledata <- read.csv2('sampledata2.csv',skip=2)
+
+if the working directory of R was set to the directory where these
+files reside.
