Write the following methods using RegEx. The input to each function is a string, and your job is to write a function to determine if the string contains the text described.

For instance, the first function returns true in the case of "My email is [email protected]", and false in the case of "My cell phone is 555-555-5555".

1. static bool email(String s) - an email of the form [email protected]
2. static bool properName(String s) - matches a proper name like Bob, Smith, Joey
3. static bool number(String s) - a number (integer or decimal, positive or negative) 12, 43.23, -34.5, +98.7, 0, 0.0230
4. static bool ancestor(String s) - an ancestor like father, mother, great-great-grandmother. Uncles, Aunts, and Cousins are not ancestors.
5. static bool palindrome(String s) - a 10 letter case insensitive palindrome like "asdfggfdsa". Note: for this problem only assume that the whole string is either a palindrome or not a palindrome. E.g. "a abba" returns false, even though it contains a palindrome.

Please note that unit tests required...How else do you know it works. Unit tests should also include false positive testing.
