# CheckIO - O'Reilly Challenge 1 : Striped Words
# http://checkio.org

# You are given a block of text with different words. 
# These words are separated by white-spaces and punctuation marks. 
# Numbers are not considered words in this mission (a mix of letters and digits is not a word either). 
# You should count the number of words (striped words) where the vowels with consonants are alternating, that is; 
# words that you count cannot have two consecutive vowels or consonants. 
# The words consisting of a single letter are not striped -- do not count those. 
# Input: A text as a string (unicode)
# Output: A quantity of striped words as an integer.
