Rule: Enforce order of items within an class

[benjamincharity]

This rule is similar to https://palantir.github.io/tslint/rules/member-ordering/ but that rule doesn't offer the exact implementation our libraries desire.

Currently our library follows the standard:

1. properties
2. getters
3. inputs
4. outputs
5. constructor
6. lifecycle methods (these should be ordered in they are called)
   a. OnChanges
   b. OnInit
   c. DoCheck
   d. AfterContentInit
   e. AfterContentChecked
   f. AfterViewInit
   g. AfterViewChecked
   h. OnDestroy
7. public methods
8. private methods

Rule details:

• Enforce the order of items within the class according to the above list
• The rule should allow an options (obj/arr?) to customize the order
  • Note: Lifecycle method order should not be adjustable, but where the lifecycle methods are in relation to other items should be adjustable.
• Enforce 1 line break between properties, getters, inputs, outputs
• Enforce 2 line breaks between outputs and constructor and all methods

---

• Create rule
• Make the rule fixable
• Add rule to our default ruleset
