>> - Clarified parsing is case insensistive in various parse and fromXXX methods
>> - Source level cleanup based on review comments
>> - Expanded some javadoc tag text to make it more descriptive
>> - Consistent use of 'hexadecimal' vs 'hex'
>> - Review comment updates to class javadoc
>> - Review comment updates, in the example code, and to describe the characters used to convert to hexadecimal
>> - Correct length of StringBuilder in formatHex;
>> Correct bug in formatHex(char[], 2, 3) and add test for subranges of char[]
