Changed: Use RealArray instead of Vector when no algebraic operations.
to reduce repetive code. The read() call will not fail anyway (and if it does, it will be caugth by the subsequent checks). Also merge methods genThreadGroups() and getThreadGroups(). Use loops instead of lambdas in the tests for simplicity. Fixed: Swap node 3 and 4 when reading 4-noded element topology.

spatial points. The default implementation invokes ASMbase::findPoint() in a loop over the specified points. It is overridden in ASMu2DLag to perform parametric inversion for bilinear quads and triangles.
Tighten the comparison with zero tolerance (1e-8 is too loose).
nodal field at specified points defined by element index and local xi,eta parameters within those element. Added: private method evalPt() evaluating a nodal field at a point.

Added: Evaluation of 2ndary solution at specified Cartesian points.
Changed: Override evalSolPt() in ASMu2DLag with the triangle support.

This implements general point searching for unstructured 2D Lagrange meshes, for use in result point definition. It reuses some old Fortran codes of the 90s (the AFEM project) to conduct explicit parametric inversion for 3- and 4-noded shell elements.
