public function lookup_table_value(x, x_values, y_values, allow_outside) result(y_found)

Function for fast table-lookup, returns the corresponding y-value in y_values based on a given based on a given $x0$. If the allow_outside flag is given as .true. then values on the edge of the table are returned when the lookup value is outside the array. Uses simple linear interpolation.
