|We have a collection of Strings, and we want to right justify them.
Create a class Justifier that contains a method justify that is
given a String textIn and returns
a String containing the same Strings, right justified, in the same order as they
appear in textIn.
The returned Strings should be padded on the left with space characters so that they are all the same length as the longest String in textIn.
|-||textIn will contain between 1 and 50 elements inclusive|
|-||each element of textIn will contain only uppercase letters 'A'-'Z'|
|-||each element of textIn will contain between 1 and 50 characters inclusive|
