Removed debug output.
extracted line duplication to seperate function
new points are now added to lines
new geo name is given as parameter
implemented updating of polyline node indices + real data modifications
fixed index error in GeoTreeItem where name changes to surfaces would result in a crash when the geometry did not contain polylines
Merge branch 'master' of https://github.com/ufz/ogs into GeoTreeModelBugFix
Merge pull request #226 from rinkk/GeoTreeModelBugFix

Geo tree model bug fix
Merge pull request #224 from norihiro-w/fix-warnings

Fix compiler warnings due to comparison of signed and unsigned
Merge pull request #198 from norihiro-w/add-element-static-functions

Add constants to mesh element classes
fixed a sign-error and optimised the code
replaced nearest neighbour technique with triangle-line-intersection for mapping of geometry on mesh
removed elevation calculation as this will be applied laterfor all nodes via collision detection
moved collision detection methods to AnalyticalGeometry, added fixes based on pull request comments
Merge pull request #228 from rinkk/TriangleLineIntersection

Geometry on mesh mapping via Triangle-Line-Intersection
Updated converter submodules.
add FemEnums.h
add ShapeMatrices
add NaturalCoordinatesMapping
include Eigen in Tests if OGS_USE_EIGEN
