Case insenstive setting presumes keywords are lowercase?

Thanks for the code. I noticed that for case insensitive matching, Trie.parseText() reduces the input text to lower case but the keywords are left in their original case (as added). So for the situation where
trie.addKeyword("Alpha");
and
Collection emits = trie.parseText("Alpha");
no matches are returned when case insensitive = true

Adding
if (trieConfig.isCaseInsensitive()) {
character = Character.toLowerCase(character);
}
to addKeyword would make addKeyword and parseText symmetric and match all combinations of case.

thanks
