shortened Game attribute "use_random_fill" to more common "random_fill".
Specified and implemented Advisor for managing a versus game. More complex
than capture due to incremental nature of the simulation. Need to be able
to provide results of each turn before trying next since next turn could
take too long and need to be ignored.
Changed specification to ignore destructions of empty or wildcard-only groups.
Moved capture profile into tests folder.
Update readme descriptions. Also added example command line usage
for Versus and Capture. Finally, added a "manual" folder within tests
to test the example code that is used in the readme.
