Vowel Harmony
Takka has a simple progressive vowel harmony system based on roundness. Each vowel has two variants, and there are four rules for harmony:
 * 1) In the enviroment that there is either a rounded or an unrounded vowel as the last vowel in the word and a vowel of a different type is added, rule no. 2 is applied.
 * 2) E and É, I and Í are interchangeable in harmony, while A and Á, U and Ú aren't.
 * 3) E and É and I and Í can be substituted in harmony, while only Á and Ú can be harmonised (into A and U respectively).
 * 4) Harmony is applied only to suffixes (not to infixes, compounds etc.)
