         -u1,v1 are  the parameters of the point on Surf1 <br>
      -u2,v2  are  the  parameters of the point on Surf2 <br>
      -Order  is the required continuity: <br>
       GeomAbs_C0    GeomAbs_C1  GeomAbs_C2 <br>
       GeomAbs_G1 GeomAbs_G2 <br>

-EpsNul is used to detect a a vector with nul
magnitude

-EpsC0 is used for C0 continuity to confuse two
points (in mm)

-EpsC1 is an angular tolerance in radians used
for C1 continuity to compare the angle between
the first derivatives

-EpsC2 is an angular tolerance in radians used
for C2 continuity to compare the angle between
the second derivatives

-EpsG1 is an angular tolerance in radians used
for G1 continuity to compare the angle between
the normals


-Percent : percentage of curvature variation (unitless)
used for G2 continuity

      - Maxlen is the maximum length of Surf1 or Surf2  in <br>
      meters used to detect null curvature (in mm) <br>

the constructor computes the quantities which are
necessary to check the continuity in the following cases:

case C0
-----—

• the distance between P1 and P2 with P1=Surf (u1,v1) and
  P2=Surfv2(u2,v2)
  
  
  case C1
  ----—
  
  
• the angle between the first derivatives in u :
  
  dSurf1(u1,v1) dSurf2(u2,v2)
  --------— and ------—
  du du
  
  the angle value is between 0 and PI/2
  
  
• the angle between the first derivatives in v :
  
  dSurf1(u1,v1) dSurf2(u2,v2)
  -----— and ------—
  dv dv
  
  
• the ratio between the magnitudes of the first derivatives in u
  
• the ratio between the magnitudes of the first derivatives in v
  
  the angle value is between 0 and pi/2
  
  case C2
  ----—
  
• the angle between the second derivatives in u
  2 2
  d Surf1(u1,v1) d Surf2(u2,v2)
  -------— -------—
  2 2
  d u d u
  
  

the ratio between the magnitudes of the second derivatives in u

• the ratio between the magnitudes of the second derivatives in v
  
  the angle value is between 0 and PI/2
  
  case G1
  ----—
  -the angle between the normals at each point
  the angle value is between 0 and PI/2
  
  case G2
  ----—
  
  • the maximum normal curvature gap between the two
    points
