solving the bugs in arclength
running arclength again
Merge pull request #39 from nicola-giuliani/arc_bugs

Fixed arclength bugs.
Uncommented test-arclength and added docs to VectorSpace.
Vectorial test for least_square
Merge pull request #40 from ESeNonFossiIo/fix-least-square

Vectorial test for least_square
Added some tests for derivative, and operator *= n to VectorSpace.
Merge pull request #41 from luca-heltai/uniform-piecewise-vspace

Added some tests for derivative, and operator *= n to VectorSpace.
changing the arclength to let it take more control points
it seems ok for multiindices
working on different CP sets. i hope test ok
Fixed bug in affine space for derivativees higher than 1.
Merge pull request #42 from nicola-giuliani/new_arky

Arclength parametrization for different control points
Merge pull request #43 from luca-heltai/fix-affine-vspace

Fixed bug in affine space for derivativees higher than 1.
Rename arclength_example.py to applications/arclength_example.py
Tried to resolve issues in ipynb file.
Fixed tiny issue in __init__.py
Added possibility to evaluate interpolation matrix of derivative.
