User
 data
  Makes a histogram from the user data, to be given either (a) globally, as a set of individual values, or (b) in classes (all with the same width). In the latter case, data must be given as: 'centre of the 1.st class', 'centre of the last class', followed by all the 'class frequencies' (counts).
  [Get data for another case (open another browser window, and copy and paste).]
  * Parameters are calculated by the program iff the following are null:  both 'class boundaries'; 'klasses' and or 'width'. (If both these are given, the former prevails.)
Use no "tab" characters.
