Sal's Flamenco - staircase routing for back and top purflings

A deeper rout into the back is for the purfling (laminated walnut/maple veneer), resembling a staircase.

The "staircase" goes all the way round, stopping at the neck.

The top has a deeper rout to feature a double-purfling.

The router (grey) behind the guitar takes a deserved rest.
