Set up the sketches and tested some demos for the Factory Method Pattern and Reflection
Applied the pattern to the LSB algorithm, mainly changed the InputViaText class and the DecodePasswordInput class
1.Applied the pattern to F5 algorithm, specifically implemented the F5Algorithm class.
2.Added a spinner in the Option menu to specify the algorithm used to embed or extract messages.
1. Updated the InputViaFile class as a client to the Factory Method Pattern.
2. Fixed a bug in F5 Algorithm which happens when trying to decode other forms of images.
Moved some classes to new packages to make the project neater, and did some minor changes.
