  implement fin[] function from arXiv:hep-ph/0210258

In mt.res one can find the following definition:

functions fin(mm1,mm2) defined as
if mm1>mm2
 fin(mm1,mm2)=(-7/2 - (7*mm2)/(2*mm1) +
  PolyLog(mm2/mm1) - (mm2*PolyLog(mm2/mm1))/mm1 -
  (3*mm2*Log(mm1))/mm1 - Log(mm1)*Log(mm1 - mm2) +
  (mm2*Log(mm1)*Log(mm1 - mm2))/mm1 + (3*mm2*Log(mm2))/mm1 -
  Log(mm1)*Log(mm2) + (2*mm2*Log(mm1)*Log(mm2))/mm1 +
  Log(mm1 - mm2)*Log(mm2) - (mm2*Log(mm1 - mm2)*Log(mm2))/mm1 - PI^2/4 +
  (mm2*PI^2)/(12*mm1) + Log(mm1)^2 - (3*mm2*Log(mm1)^2)/(2*mm1) -
  (mm2*Log(mm2)^2)/(2*mm1));
if mm1<mm2
 fin(mm1,mm2)=(-7/2 - (7*mm2)/(2*mm1) -
  PolyLog(mm1/mm2) + (mm2*PolyLog(mm1/mm2))/mm1 -
  (3*mm2*Log(mm1))/mm1 + (3*mm2*Log(mm2))/mm1 +
  (mm2*Log(mm1)*Log(mm2))/mm1 - Log(mm1)*Log(-mm1 + mm2) +
  (mm2*Log(mm1)*Log(-mm1 + mm2))/mm1 + Log(mm2)*Log(-mm1 + mm2) -
  (mm2*Log(mm2)*Log(-mm1 + mm2))/mm1 + PI^2/12 -
  (mm2*PI^2)/(4*mm1) + Log(mm1)^2/2 - (mm2*Log(mm1)^2)/mm1 -
  Log(mm2)^2/2);
if mm1=mm2
   fin(mm1,mm1)=-7-PI^2/6;

where PolyLog(x)=PolyLog(x,2)=Spence(1-x) dilogarifm function
