Consultation about SSCF calling

a) Hello, when I try to call ```SSCF```, I will encounter the following error, could I ask you how to solve it? There is no error when calling ```kind= "SCF"``` or ```kind= "IB"```.

The code is as follows.
```
from biorefineries import cellulosic
import biosteam as bst
bst.nbtutorial()
cs = cellulosic.Biorefinery('corn stover ethanol')
chemicals = cs.chemicals
bst.settings.set_thermo(chemicals)
Feedstock = bst.Stream(
ID='Feedstock',
price=0.0516,
total_flow=1000,
units='kg/hr',
Glucose=1,
)
fermentation_sys = cellulosic.create_cellulosic_fermentation_system(
ins=Feedstock,
mockup=True,
kind="SSCF"
)
```
The error information is as follows.
```

TypeError: create_simultaneous_saccharification_and_cofermentation_system() got an unexpected keyword argument 'cofermentation_reactions'
```

b) Could I ask you what is the difference betweem ```mockup=True``` and ```mockup=False``` when calling above ```fermentation_sys```, does ```mockup=True``` or ```mockup=False``` make any difference to the result (simulation result, TEA result, LCA result).

c) In addition, could I ask you what is the difference between ```SaccharificationAndCoFermentation``` (https://github.com/BioSTEAMDevelopmentGroup/Bioindustrial-Park/blob/master/biorefineries/cellulosic/units.py#L511) and ```SimultaneousSaccharificationAndCoFermentation``` (https://github.com/BioSTEAMDevelopmentGroup/Bioindustrial-Park/blob/master/biorefineries/cellulosic/units.py#L620)? It seems that both units are Saccharification and CoFermentation occurring simultaneously.

Thanks for your help. Wish you a good day.
