+ * 	Count the Vowels
+ * ------------------
+ * 
+ * A vowel is a syllabic speech sound pronounced 
+ * without any stricture in the vocal tract. 
+ * Vowels are one of the two principal classes of 
+ * speech sounds, the other being the consonant. 
+ * Vowels vary in quality, in loudness and also in quantity.
+ * 
+ * The letters a, A, e, E, i, I, o, O, u and U are called vowels. 
+ * The other letters in the alphabet are called consonants.
+ * 
+ * 
+ * say the string is "Hello"
+ * the vowels are {e, o}
+ * Count is 2
+ * 
+ * say the string is "Tamil"
+ * the vowels are {a, i}
+ * Count is 2
+ * 
+ * say the string is "why"
+ * there are no Vowels in this word
+ * Count is 0
