    0030322: Remove DRAW-command "mesh" as useless
    
    In fact, the DRAW-command "mesh" is duplicate of "incmesh".
    
    The difference is that the "mesh" creates DRAW-object MeshTest_DrawableMesh. However, this object is currently not applicable (e.g. we cannot display it).
    
    DRAW-commands "mesh", "addshape", "smooth", "edges", "vertices", "medge", "mvertex", "triangle", "dumpvertex", "dumpedge", "dumptriangle" and "onetriangulation" have been removed.
    
    The class MeshTest_DrawableMesh has been removed as useless.
    
    Testgrids "mesh standard_mesh" and "mesh advanced_mesh" have been removed.

    0030008: BRepMesh does not respect angular deflection in internal area of bspline surface
    
    1. Check whether the mesh satisfies the required angular deflection has been amended. Namely normals (to the surface) in the ends of any not "frontier" link are made collinear (with the given angular tolerance).
    
    2. New parameters AngleInterior and DeflectionInterior have been added in IMeshTools_Parameters structure.
    
    3. In case of thin long faces with internal edges, add points of internal edges to control parameters using grabParamsOfInternalEdges() in order to avoid aberrations on its ends. Disable addition of parameters from boundary edges in case of BSpline surface. Deviation can be controlled through the deflection parameter.
    
    4. Grab parameters from edges in case if there is just a single interval on BSpline surface along U and V direction.

    0030305: Strange logic in BRepMesh_Deflection::ComputeDeflection(...) method
    
    Before the fix, angular deflection was scaled to some coefficient in the method BRepMesh_Deflection::ComputeDeflection(...). Now, angular deflection is constant.

    0026106: BRepMesh - revision of data model
    
    Removed tight connections between data structures, auxiliary tools and algorithms in order to create extensible solution, easy for maintenance and improvements;
    Code is separated on several functional units responsible for specific operation for the sake of simplification of debugging and readability;
    Introduced new data structures enabling possibility to manipulate discrete model of particular entity (edge, wire, face) in order to perform computations locally instead of processing an entire model.
    
    The workflow of updated component can be divided on six parts:
    * Creation of model data structure: source TopoDS_Shape passed to algorithm is analyzed and exploded on faces and edges. For each topological entity corresponding reflection is created in data model. Note that underlying algorithms use data model as input and access it via common interface which allows user to create custom data model with necessary dependencies between particular entities;
    * Discretize edges 3D & 2D curves: 3D curve as well as associated set of 2D curves of each model edge is discretized in order to create coherent skeleton used as a base in faces meshing process. In case if some edge of source shape already contains polygonal data which suites specified parameters, it is extracted from shape and stored to the model as is. Each edge is processed separately, adjacency is not taken into account;

Dear Mikhail,

Please review CR30322 branch (for OCCT) and CR26106prod_final branch (for OCCT-products).

Test results are here: http://jenkins-test-12.nnov.opencascade.com/view/CR30322-CR26106_NBV/

tests/mesh/end
- Please update the script so that no mesh command at all.
