Brief overview

• This library comes with the BitValue enum, wich has two values, BitValue.ZERO and BitValue.ONE.
• You can create a BitList (an efficient implementation of List<BitValue>) to store them.
• You can use BitListConversions to convert between byte,int,long,String and BitList.
• The BitReader is a wrapper around InputStream that allows the user to read bit by bit.
• The BitWriter is a wrapper around OutputStream that allows the user to write bit by bit.
• The flush method of BitWriter ignores the last bits if they are not part of a byte.
• The BitWriter has a addPadding method that adds zeros to complete the byte.
• The BitListInputStream it's an implementation of InputStream that reads from a List<BitValue>.
• The BitListOutputStream it's an implementation of OutputStream that writes to List<BitValue>.
