The APIs have access to the solid data, and I fixed a bug: Basically, the template parameter for std::bitset expects an integer representing the number of bits to hold, but I initially misread it as the number of bytes. This has been corrected. I've also added a sandy beach to the generated island. I'm tempted to start working on some simple generators soon.
