Adding text suggestions for Validators and Simple Validators

[lukejagodzinski]

A lot of changes, thanks for this PR. I will check it and merge. What I've notice after quick checking is that you made an error in the or validator example. Could you fix it?

Hi, thanks for response. Would you prefer that I isolate each page as separate PRs?

As for the or validator example, are you referring to this:

and

Validators.and(validatorsList);

The and validator takes an array of validators as the first argument and its function is to check whether the value of the field passes validation of all validators from the list.

// firstName has to be a string that is at least 3 characters long
validators: {
  firstName: Validators.and([
    Validators.string(),
    Validators.minLength(3)
  ])
}

or

THIS PART HERE?: vvv I think this is correct because you're defining an and validator using a simple array.

validators: {
  firstName: [
    Validators.string(),
    Validators.minLength(3)
  ]
}

Yes simple array is the and operator but you've provided simple array in the or validator which is not correct. You should provide simple array inside Validators.or(simpleArray).

If it's not a big problem for you I would be glad if you could create separate PRs for each page :). Thanks to that I could just review it and merge one by one :). Thanks for a help with proofreading documentation :)

Ok, I'll do separate PRs from now on.

Oops. You were right on the or example. I updated my branch.
