CHANGELOG

3.0

Combines syllables and consonant_clusters into structure.
- It's still possible to access all functions through the package's global namespace.
Adds structure.get_cv() which finds the consonant-vowel structure of a word.
Removes get_neighbors() and filter_words(), which were deprecated in 2.0.

Adds check_neighbors(), which checks whether two words are neighbors. Reduces redundant code in neighbor-getting functions, and allows for boolean comparison of two words.
Adds clusters_word(), which gets the consonant clusters for a single word, in contrast with clusters(), which gets the consonant clusters of a list of words.
Fixes bug where lists provided as arguments were emptied. Now uses list.copy().

Adds get_neighbor_positions(), which determines the position at which a substitution neighbor relationship is formed.

Adds get_neighbor_types(), which determines the type of neighbor relationship (deletion, addition, or substitution) for sets of neighbors.
Splits get_neighbors() into two functions (get_neighbors() is now deprecated and should be removed in the next minor release):
- get_neighbor_dict(), which is essentially the original, useful for when you want a list of all the neighbors for particular words,
- get_neighbor_pairs(), which returns a list of (word, neighbor) pairs, useful for when you want a list of all the unique neighbor pairs in a lexicon without specific interest in any individual words.
No longer uses pandas; instead uses csv, which is in the standard library. This changes the arguments of get_words() slightly: sep is now delimiter, and the default value is now "," (was "\t"). Also allows for the use of any csv.DictReader formatting parameters.
filter_words() is now filter_by_nsyll(), for improved clarity. filter_words() is deprecated and should be removed in the next minor release.
