Added missing headers
Merge pull request #4 from babrodtk/vs_2012_compilation_fix

Added missing headers (functional)
Fixed bug in subcurve due to reversed orientation.
Added more stable method for setting the span vectors.
Merge pull request #8 from SINTEF-Geometry/parallel_vec_fix

Parallel vec fix
Replaced epsgeo with epspar for parameter curve calculation, added debug function.
setSpanningVectorsSafe(): Choosing better values vec1_ and vec2_, i.e. with normal_ = z_axis, we set vec1_ =  x_axis and vec2_ = y_axis, etc.
Merge branch 'parallel_vec_fix'
No need to retesselate if the resolution is unchanged.
Fixed various bugs related to trimming of parametric surfaces.
Added date and build info to about() function in gvApplication.
Current bugfix.
Added std:: prefixes to the ostreams in the file.
Makes it easier to build instead of requiring the user to have a using directive.
Support for 1D LRSplineSurface.

Lifting the 1D surface to 3D by adding parameter domain as X and Y coordinates.
Fixing bugs related to projection of curves.

Cleaned up the usage of unspecified "tol" variables. When derived from
a geometric tolerance and used as a parametric tolerance, we now
calculate a more suitable parametric tolerance using the global size
of the surface in the corresponding parameter directions.
