motionSmootherAlgoCheck::checkMesh: improved minVol test and removed unused tests

Browse Source 
motionSmootherAlgoCheck::checkMesh is used by snappyHexMesh to check the mesh
after snapping and morphing.  The minVol test which checks for collapsed cells
is now relative to the cube of the minimum bounding box length so that it is
less dependent on the size of the geometry and less likely to need changing for
very small geometries.

The default value is set in
etc/caseDicts/mesh/generation/meshQualityDict
etc/caseDicts/mesh/generation/meshQualityDict.cfg

//- Minimum cell pyramid volume relative to min bounding box length^3
//  Set to a fraction of the smallest cell volume expected.
//  Set to very negative number (e.g. -1e30) to disable.
minVol 1e-10;

The unused minArea and minTriangleTwist tests have been removed
