Non-alphabetical charachters don't change in the transformed text.

The transformed text is given in lower case.

2 - Example

For "abc def" and a key of 1 the return value will be : bcd efg

3 - Usage

caesar [options] <text>

Options : 
-h, --help          output usage information
-d, --integer<n>    Right shift, must be a number (if it's a float the integer part will be considered )

NB : if the text contains spaces, use "text text"
