A simple MP that aims for a reference catch (as a proxy for MSY) subject to imperfect information.

Note that this is my interpretation of their MP and is now stochastic. Currently it is generalized and is not 'tuned' to more detailed assessment data which might explain why in some cases it leads to stock declines.

The TAC is calculated as:

*\textrm{TAC} = C_\textrm{ref}*

where *C_\textrm{ref}* is a reference catch assumed to be a proxy for MSY.
In the MSE *C_\textrm{ref}* is the calculated MSY subject to observation error
defined in `[email protected]_Cref`

.

The TAC is subject to the following conditions:

if next TAC > 1.2 last catch, then TAC = 1.2 last catch

if next TAC < 0.8 last catch, then TAC = 0.8 last catch

An object of class `Rec`

with the `TAC`

slot populated with a numeric vector of length `reps`
