Message:

New class TriangleIntersection List and (hopefully) final fix of CorrelationToSurface().

• Distances to surface were still calculated between the vector and the triangle plane not the triangle itself. Although functions such as BoundaryTriangleSet::GetClosestPointInsideTriangle had already been written.
• As in class Tesselation there were many functions that all did the same: Calculate intersections between a point and all closeby triangles and then get the intersection or calculate this minimum distance and so ...
• ... this was all put into a new class (in a new file): TriangleIntersectionList whose constructor scans all nearby triangles and put the calculates Intersections in the triangle into a list.
• Functions as IsInside(), GetSmallestDistance(), GetClosestIntersection() and GetClosestTriangle() bring the desired functionality to the outside.
• Respective functions in class Tesselation just make use of this new class and its member functions.
• CorrelationToSurface() also directly instantiates this class to effectively use two of its functions.
• Makefile.am has this new file in its SOURCES and HEADERS.
• Tesselation:GetDistanceSquaredToSurface() -> Tesselation:GetDistanceToSurface(), FillBoxWithMolecule() has been adapted to this change.

AnalysisCorrelationToSurfaceUnitTest:

• still has errors in it, as the distance were wrong before (because with respect to triangle plane, not triangle). Hence, the test was corrected.
