Release notes:

Breaking changes

• Changed matrix_pivot! to simply pivot! and eliminated the basis_pivot! function.
• find_pivot now returns i,j where i is the row and j is the column of the pivot.

Other changes

• Rebuilt find_a_basis.
• T[i,j] returns the i,j-entry of a tableau, T. This is read-only. Note that the header row is row 0 and the z column is column 0.
• New dual_basic_vector function.
