Fixed the Toroidal surface recognition; The test case bugs/moddata_1/bug22296: the result is a torus with parameters: u [0, 2*PI], v [PI, 3*PI]; The test case bugs/modalg_5/bug23954: BAD -> OK.
Splitting of subgroups bugs/modalg and bugs/moddata to optimise time of testing Correction of end file in group v3d Small correction of test case
