ruby-caesar_cipher

Working through the TOP section on Ruby fundamentals, the first project to work on is to create a caesar cipher.

We have to have a function such that:

• A user can pass a string through with punctuation and a shift count
• The function will modify only alphabet characters [a-z][A-Z] ignoring punctuation and space characters
• The function will wrap the character shift from z to a and Z to A when shifting past the end of the alphabet
• The function will not change the case of the characters

Example

>caesar_cipher("What a string!", 5)
=> "Bmfy f xywnsl!"
