Feature/check boundaries layer

add check of boundaries layer :

• attribute bnd_type must be defined
• point of each boundaries line must be inside contour lines

To check if boundaries line are inside contour :

• create lines from polygon contour
• create buffer of 1m around contour lines
• extract vertices of each boundaries lines
• count number of vertices inside buffered contour lines

=> boundary line is inside contour is all vertices are inside one buffered contour lines
