[$any] Add sort functionality

[jimdebeer]

[jimdebeer]

use keys if there is sort, uses a 'sort' subscription all on $any

[jimdebeer]

need to subscribe on the fields that are being sorted on (this is a bit harder)

[jimdebeer]

needs to be able to dynamically change sort as well (so the sort field can be a subscription to another state object that gets computed)

[jimdebeer]

syntax

how do you know you want to sort on a field (straight) or you want to subscirbe on a field that can change?

[jimdebeer]

is sort really an $any functionality? -- can also sort objects etc
@youzi what are we going to do here?

[jimdebeer]

reuse some algos from base (check how to do this)

[jimdebeer]

• needs optimisation and edge cases
• switching on references
• other sort from subscription then the sort in the state
• find best way to do updates
