0026261: Create a tool to remove tails from any wire
A tool to remove tails from the wires of a shape was created.
The tool is based on mechanism 'ShapeFix',
is located in types 'ShapeFix_Wire' and 'ShapeAnalysis_Wire',
is enabled through method 'ShapeFix_Wire::FixTailMode' and
is initialized by methods 'ShapeFix_Wire::SetMaxTailAngle' and 'ShapeFix_Wire::SetMaxTailWidth' and
is called through method 'ShapeFix_Wire::FixTails'.
The status of any performing of the last method is accessible through method 'ShapeFix_Wire::StatusFixTails'.
The tail angle is checked only at the tail start.
Mechanism 'ShapeFix' was modified:
- the tool is disabled by default;
- algorithm 'Fix notched edges' is disabled then the tool is enabled;
- the tool and the last algorithm work in turns then the tool works on the request.
'Draw' command 'fixshape' was extended by options '-maxtaila' and '-maxtailw' to test the tool.
'Draw' tests to test the tool were created.
Algorithm 'fixshape' was changed in type 'ShapeProcess_OperLibrary' to
- use new parameters named 'FixTailMode', 'MaxTailAngle' (in degrees) and 'MaxTailWidth' from the algorithm context;
- apply the tool after the shape will be fully fixed if the tool was enabled.
Place holders for the new parameters were created in the resource file of mechsnism 'STEPControl_Reader'.

2. The cache is used now in corresponding adaptor classes (Geom2dAdaptor_Curve, GeomAdaptor_Curve and GeomAdaptor_Surface) when the curve or surface is a B-spline.
