Initial commit

Commit: c0a658b, Parent(s): c505e14, Author: Wayne Pollock, Date: Thu Dec 31 00:20:50 2015 -0500
Created initial test suite.
Also created skeleton comparator, and added package-info.java package description.

Commit: fa7a06f, Parent(s): c0a658b, Author: Wayne Pollock, Date: Thu Dec 31 00:24:52 2015 -0500
Worked on unit tests, enough to start working on the code itself.

Commit: 6a36836, Parent(s): fa7a06f, Author: Wayne Pollock, Date: Thu Dec 31 03:43:32 2015 -0500
Finished initial (working?) version.
Java doc API HTML looks good.
Still need to review and add more unit tests.

Commit: 90f4074, Parent(s): 6a36836, Author: Wayne Pollock, Date: Tue Jan 5 05:05:35 2016 -0500
Completed unit test suite.
Also fixed copy-paste bug with BigInteger constructor reusing s1 (now uses s2).
Added @Throws to method compare's doc comment, to document it must (by
contract) throw NullPointerException rather than IllegalArgumentException.

Commit: 61c3f92, Parent(s): 90f4074, Author: Wayne Pollock, Date: Tue Jan 5 05:06:31 2016 -0500
Final version.
This version updated the generated Java doc HTML, and added that
directory to .gitignore.

The above Git command used an alias.  Here's how I defined the alias and a custom log format, in my .gitconfig file: 

$ # Create custom log format, use with alias command:
$ git config --global pretty.myfmt \
   'Commit: %h, Parent(s): %p, Author: %an, Date: %ad%n%B%n'
$ git config --global alias.mylog \
   'log --pretty=myfmt --full-history --branches --reverse'

$ cat .gitconfig
