/* incident.h: The header file for declaring the incident wave function.
 * Its input is the current time value (int) and its output should
 * reflect the height of the ez-field at that time on the left-hand side
 * of the computational domain. Note that since it deals with both time
 * and space it needs the value of the Courant number cdtds to know how
 * to scale those variables between each other.*/
