Implement Aliases

[erfanium]

Sometime I need use a same validation rule in some places, aliases (or whatever name is better) are great for this case.
For example, I define an alias for my username validation rule:

v.alias('username', {
   type: 'string',
   min: 4,
   max: 30
   regex: ...
  ....
})

Then, I can use this alias everywhere I want:

v.compile({
   firstName: 'string',
   email: 'email',
   username: 'username'  // using alias 
}) 

also, extending aliases!

v.compile({
   firstName: 'string',
   email: 'email',
   username: {
      type: 'username',
      optional: true,
      max: 60
   }
})

Coverage remained the same at 100.0% when pulling e300c40 on erfanium:master into ddd8ec2 on icebob:master.

Good idea. Please don't push code style changes because hard to check the relevant changes.

Fixed.
To avoid this problem, it's better to use Prettier , etc...
