FIX to The Wavelet Matrix: An Efficient Wavelet Tree for Large Alphabets

Level: Small

In Figure 1 right, the last line should start 0 1 1 1..., not 0 0 0 1.

In Figure 5, line 5, the c_16 should have been c_32.

In Algorithm 5, the code for acc(l,i), line 7 should read "i <- z_l + rank_1(B_l,i)" (it misses "z_l + ")
