In response to referee's comment:

"However, (although it is probably not important for model developers), I was
still unable to load the model ‘Meinhardt 1976 with growth’ example from the
‘Models’ drop down menu, I got the ‘Fatal error’ message ‘stepwise underflow in

rkqs, with h=0.000000 and htry = 0.100000’. The model did work when I selected
the Meinhardt model in both the Models and the File -> Read leaf menus together,
it would be preferable if the models loaded from the Models menu worked

automatically. I am not sure that the update referred to in the author’s
response permits the loading of ‘My First Model in Virtual Leaf’ from the
‘Models’ drop down menu; I only got a cell that wiggled."

I made the following changes:

- meinhardt_plugin now reads "meinhardt_init.xml" by default
- changed the name of 'My First Model in Virtual Leaf’ to '0: Empty model template (does nothing)' to make it clear that the wiggle cell is the intended behavior for this model example.
- Added default parameter files for Tutorial1A-D and Tutorial2 to prevent variable behavior depending on the last parameter settings used.
