tk_pfn.graph() is a grapher of solutions of Pfaffian equations in x and y (fixed).
tk_pfn.graph(Pf,Dom,Iv,Step)  Pf=[P_1,P_2] where dF/dx=P_1 F, dF/dy=P_2 F
Dom=[[xmin,xmax],[ymin,ymax]],  Iv is the initial value of F at [xmin,ymin], Step is a step size.
An example can be found in tk_pfn.testgraph1().
