Generic Configuration Parameters
- boundaryFlags (string, optional)
- The tokens to process must be inside two vertex mark with this flags (e.g ["TEXT_BLOCK_SPLIT"])
- skipFlags (string array, optional) - Flags to be skipped by this stage
- Tokens marked with this flags will be ignore by this stage, and no process will be performed.
- requiredFlags (string array, optional)
- Tokens need to have all the specified flags, in order to be processed.
- atLeastOneFlag (string array, optional)
- Tokens will need at least one of the flags specify in this array.

Output Flags
Note that flags are placed on every token as appropriate to the current token:
- If the token is "President" then that token will have the TITLE_CASE flag.
- If a new lower-case normalized interpretation, "president" is added as an alternative, this alternative will have the "ALL_LOWER_CASE" flag.
Lex-Item Flags:
- TOKEN - All tokens produced are tagged as TOKEN
- ALL_PUNCTUATION - Tokens processed or produced composed only of punctuation characters are tagged as ALL_PUNCTUATION
- HAS_DIGIT - Tokens produced with at least one digit character are tagged as HAS_DIGIT
- HAS_PUNCTUATION - Tokens produced with at least one punctuation character are tagged as HAS_PUNCTUATION. (ALL_PUNCTUATION will not be tagged as HAS_PUNCTUATION)
Vertex Flags:
- CHAR_CHANGE - Identifies the vertex as a change between character formats

- If the token being processed is "token.123", the parameter "punctuation" is set, then one of tokens generated should be "." and it will have the ALL_PUNCTUATION flag.
- If the token being processed is "token.123", the parameter "punctuation" is NOT set, then one of tokens generated should be "token." and it will have the HAS_PUNCTUATION flag.

- ALL_PUNCTUATION - Tokens processed or produced composed only of punctuation characters are tagged as ALL_PUNCTUATION.
- HAS_DIGIT - Tokens produced with at least one digit character are tagged as HAS_DIGIT.
- HAS_PUNCTUATION - Tokens produced with at least one punctuation character are tagged as HAS_PUNCTUATION. (ALL_PUNCTUATION will not be tagged as HAS_PUNCTUATION).
- ALL_DIGITS - All characters in the token are digits.
- HAS_LETTER - At least one character is a letter.
- ALL_LETTERS - All characters in the token are letters.
- SPLIT - Tokens split are tagged with SPLIT.
