Detailed Description
Fractional operator class.
This class is used for any RT-operator which operates on fractional coordinates. For a full list of methods, see clipper::RTop

constructor: from string description
Construct an RT operator from a string description, e.g. 1/2x,z-y+2/3,x '*' is optional for multiplication, commas are compulsory.
