% DESCRIPTION: HISTORY History object class constructor.
%              Create a history object.
%
% SUPERCLASSES: ltpda_nuo < ltpda_obj
%
% CONSTRUCTORS:
%
%              h = history()
%              h = history(proctime, minfo, plist)
%              h = history(proctime, minfo, plist, in_names, oldUUID, in_hists)
%
%              h = history(filename)
%              h = history(structure)
%              h = history(history-object)
%              h = history('database', ...)
%
% INPUTS:      minfo:    Minfo-object which is created in the called method.
%              plist:    Plist-object which is used in the called method.
%              in_names: Variable names which are used for the called method.
%              in_hist:  Older history-objects
