Defines a parallel cartesian grid surface mesh.
Class to define a surface mesh represented by a grid, with cartesian coordinates, of which the lines are parallel to X-axis or Y-axis. This mesh is defined by num_y vertical lines and num_x horizontal lines. x is an array of num_x floats, and y is an array of num_y floats.
The values on the mesh nodes are defined by the PbMesh::addValuesSet(set_index,val) method, where val argument is an array of num_x * num_y floats.

Find the mesh's cell that contains the point.
If the (optional) adjacent cell is given, searching the containing cell starts by the cells around this adjacent one. Returns also the parametric coordinates of the point in the found cell. Parametric coordinates are the coordinates of the point relative to a topologically equivalent unit cell. A point is inside a cell if its parametric coordinates range from 0 to 1. However we use a test with a tolerance value: a point is inside the cell if its parametric coordinates p verify -tolerance <= p <= 1+tolerance. Parametric coordinates are useful to interpolate the value in the cell (see PbCell::getValue). Attention! This method returns always the same address of an internal private cell. This private cell is updated each time findContainingCell is called. If the cell exists, it returns a PbPixelCell for a 2D mesh, or a PbQuadrangleCell for a 3D mesh.
