Do some actual analysis

[gabebw]

It'd be nice if this happened:

$ most-used --analyze
Your most-used command is: g
Your most-used command that would probably be better as an alias is: heroku
Here's the top 25% of your commands:
30 g
10 heroku
5 spring

Maybe print commands that would maybe be better as an alias in yellow?

"Maybe be better as an alias" can just mean "over 5 characters", or do some Fancy Math where each command's value is length * (number of times used) and it's better as an alias if it's in the top 25% of values across all commands. Maybe even check arguments too!

Tests to write:

• It should not suggest aliasing 1-character commands
• 246 gcm will almost always be at the top for me - maybe weight the length name a little more relative to the frequency?

I have a spike going in the gbw-analysis branch.
