## error handling

- using the macro __FUNCT__ to define routine names; Newton methods to solve u'' + u^{2} = f in parallel.
  This example employs a user-defined monitoring routine and optionally a user-defined
  routine to check candidate iterates produced by line search routines. This code also
  demonstrates use of the macro __FUNCT__ to define routine names for use in error handling.
