Message:

New functions vor class Vector and Matrix.

Matrix:

• transpose() (returning copy and on itself)
• zero() (initialize to zero)
• transformToEigenbasis() (columns are eigenvectors, return value has eigenvalues)

Vector:

• GreatestComponent() (yields index of greatest component)
• SmallestComponent() (same for smallest)

File:

• src/LinearAlgebra/Vector.cpp (modified) (2 diffs)
