// Spellchecker
// Wrapper for the IBDAWG class.
// Useful to check several dictionaries at once.

// To avoid iterating over a pile of dictionaries, it is assumed that 3 are enough:
// - the main dictionary, bundled with the package
// - the extended dictionary, added by an organization
// - the personal dictionary, created by the user for its own convenience
