Implement specific class for Gauss-Lobatto Lagrange polynomial

[rafaelrojasmiliani]

• [x] with sum operations with other GaussLobatoLagrange GSpline.
  • This require to test
    1. If the basis are the same
    2. If they have both the same number of intervals
    3. If they have both the sames dimension of co-domain
• [x] #45
• [x] multiplication by real scalar
• [x] multiplication by scalar valued GSpline
• [x] division of a real number by a scalar valued GSpline
• [x] assignment multiplication by real scalar (consider write this for splines)
• [ ] Matrix multiplication, left (transpose) and right
• [ ] Multiplication by a history of matrices (Different matrix for a different instances) left (transpose) and right
• [x] euclidean norm, takes a spline and returns a scalar valued spline.
• [x] dot product
• [ ] #49
