Detailed Description

File system abstraction
Provides standard operations on the filesystem, (a bit like FUSE)

API using FileSystem only used sandbox-side path. FileSystem should be the
only object able to interact with real path, outside the sandbox.

Thus, if `resolve_path` is correctly implemented and used, it should not be
possible to modify files outside the sandboxed path
