Profile Definition Thick Trailing Edge

[GoogleCodeExporter]

There are some issues with interpreting the relative coordinates of a profile 
if the trailing edge is thick and does not end on the same x-position. 

It is read by TIGL in this way: 

A trailing edge point is defined as the middle between the last point on the 
upper and lower surface. The chord line passes through the leading and trailing 
edge point. On each surface xis = 1 is at the intersection of the chord line 
and a perpendicular line through the trailing edge point of that surface. 
Attention: This means that xsi may differ for upper and lower surfaces of 
profiles with thick trailing edges that end at different x-positions.

All reverse! No open, crooked trailing edges of profiles are allowed.

No changes to the schema itself are necessary. Nevertheless, need to update the 
documentation

In addition, thick trailing edges should be possible for the CST profiles as 
well:

Bei der CST-Parametrisierung von Profilen wäre ein zusätzlicher optionaler 
Parameter (z.B. TrailingEdgeThickness) für Profile mit endlicher 
Hinterkantendicke wünschenswert, wie in Kulfans Papers beschrieben (Addition 
von deltaZetaUpper = 0.5*xsi*TrailingEdgeThickness zu den z-Koordinaten der 
Oberseitenpunkte bzw. deltaZetaLower = -0.5*xsi*TrailingEdgeThickness zu den 
z-Koordinaten der Unterseitenpunkte).
