# 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 extended dictionary
# - the community dictionary, added by an organization
# - the personal dictionary, created by the user for its own convenience
