A large update to vocabulary, now with a total of over 100,000 entries.

A new text tokenizer was introduced that scans both left to right and right to left then compares the two. The scan with the least number of terms will be selected. The tokenization method used is similar in principle to previously. It is a greedy method that scans a chunk of text using the dictionary to tokenize text selecting the set of tokens that gives the least number of tokens. Since it is greedy, it is not always optimal. Previously, this was done with only left to right scanning. The change introduced right to left scanning in addition. The left to right scan is compared to the right to left scan and the one with the least number of tokens wins. This rarely happens but it can be confusing for readers when it does. For example, consider the phrase
武裝的士兵 an armored soldier
The left to right tokenizer will select
武裝、的士、兵
The right left tokenizer will select
武裝、的、士兵
The right to left tokenizer is correct but it takes a human to figure that out. In this case the number of tokens is the same and the left will be returned, so the result is ambiguous. This is part of an ongoing effort to improve the accuracy of the tokenizer. More work is required to help users in ambiguous cases like this.

The vocabulary has been updated with new words, corrections, and references. Please let me know if you see any problems by emailing alex@chinesenotes.com.
