### Description

Calculates spawners per recruit at F=0.

This method currently does not work if any of the input objects have multiple units, seasons or areas (if dim(object)[3:5] > 1).

### Generic function

quant(ssb, rec, fbar)

### Methods

signature(ssb=FLQuant, rec=FLQuant, f=FLQuant) :
  `ssb`, `rec` and `fbar` as `FLQuant`(s)
signature(ssb=FLStock, rec=missing, f=missing) :
  `ssb`, `rec` and `fbar` are obtained from the slots of an `FLStock` object. `harvest` must have `units='f'`
signature(ssb=FLSR, rec=missing, f=FLQuant) :
  `rec` and `ssb` are obtained from an `FLSR` object, while `fbar` must be provided.
