I performed a proper management when selecting some vertices, we must detect the border with the flag BM_ELEM_SELECT in the faces around vert.

Add lambda factor for boundaries in UI.

I implemented method to exact volume preservation.

I implemented special treatment for vertices on boundaries.

Check if select faces are triangles.
Use f->len > 3, Suggested by Campbell Barton

Area constraint added.

Optimizing the code to reduce the number of accesses and loops to the structure.

Check if all faces are triangle

Add area to normalized laplacian weight.

Ready methods to calculate the Laplacian Matrix.
The OpenNL was use for solve sparse syste,.
Ready method which constructs the system of equations.
Ready method to solve the sparse linear system.

Added midpoint snapping. Will need a new icon for this. Using edge snap
icon as a placeholder.

I added several lines and file for do laplacian smooth.
At this moment the laplacian smooth is then same that smooth vertex, i did this for test functionality from operators to user interface.
