Add force and kinematics conditions
Simplified F_forma
Add formation of stiffness matrix specifically for shell element.
Add update of H coordinate. May be wrong
Change place of transition to old coordinate system. May be wrong.
Update logic for creating stiffness matrix
Add set_field to Shell sample
Finished recalculate_fields
Trying to fix bug
Fixed bug with wrong linking of non-class functions.
Add possibility to construct mesh with 4 dimensions nodes
Trying to fix wrong transition from old system to new system of coordinate
Made static mesh possible while running do step with stiffness matrix and forces put to zero
Replaced transition matrix by correct one
Fixed bug with appearance of Nan in stiffness matrix.
Fixed wrong computing of square of triangle
Fixed remesh. Now h and z of point which is inside of rectangle will be equal to average
Fixed bug
Add comment to Gauss
Add doxygen comments.
