Class CapitalizationFilterFactory

Factory for CapitalizationFilter.

The factory takes parameters:

"onlyFirstWord" - should each word be capitalized or all of the words?

"keep" - a keep word list. Each word that should be kept separated by whitespace.

"keepIgnoreCase - true or false. If true, the keep list will be considered case-insensitive.

"forceFirstLetter" - Force the first letter to be capitalized even if it is in the keep list

"okPrefix" - do not change word capitalization if a word begins with something in this list. for example if "McK" is on the okPrefix list, the word "McKinley" should not be changed to "Mckinley"

"minWordLength" - how long the word needs to be to get capitalization applied. If the minWordLength is 3, "and" > "And" but "or" stays "or"

"maxWordCount" - if the token contains more then maxWordCount words, the capitalization is assumed to be correct.
