"""
My program uses special functions to test, count, and extract vowels and consonants.
However,the string_check function uses isinstance() to check an objects type
and isinstance(obj, str) will be True only if obj is a str, and the 
vowel_or_Consonant is a boolean function that accept a text(string)as
an argument and which return either True or False and which you can call in
the program at any time to test every letter within a string to
determine whether it is a vowel or consonant.
Though, Vowel and Consonant functions return the count of each vowel and consonant.
and Anagrams_search function return a set of every possible combination,thus,
every possible Anagram.
