The functions weno_exp and tau maybe have to be changed in something new according to the following papers:

High Order Weighted Essentially Non-Oscillatory WENO-Z schemes for Hyperbolic Conservation Laws, Castro, Marcos and Costa, Bruno and Don, Wai Sun, JCP, 2011, vol. 230, pp. 1766--1792, doi:10.1016/j.jcp.2010.11.028

The weno_exp function has been deleted in commit 8b0c41b0c55127653d2d78bd6d82a59f76eee275, but two issues remain open:

  1. the role of the exponent in the tau function;
  2. the expression used to evaluate tau function.
