step-54 is now completed (it only needs comments). three different projectors have now been created in boundary_lib: normal, directional and normal_to_mesh. to adjust tolerances, a new method retrieving tolerances from a shape has been added

Fixed indentation.

fixed some problems with residual calls to Pnt() (now Point()) and axis_ intersection() (now line_intersection()) functions in boundary_lib. files coarse_sphere and coarse_circle removed from step-54 directory. also parameters.prm has been removed, and n_cycles value is asigned in an hard coded way

all input and output files have been converted to .vtk

added comments to step-54.cc

fixed all the notes by luca exept for that on the closest point function

Fixed indentation.
