RFC: Sort API

[erhathaway]

Initial thoughts are that it should should have methods:

• addToSort: (fieldName: string) => void
• incrementSortOrder: (fieldName: string) => void
• decrementSortOrder: (fieldName: string) => void
• order: { [fieldName: string]: number } // number is 1+
• removeFromSort: (fieldName: string) => void

Also, sort should be an object accessible from the manager

[mattweg-zz]

Are ordering and sorting synonymous?

[erhathaway]

Ah yes they are. Sort is probably a better name. I can change that
