Add possibility to set all parameters value through command line (without changing widgets) about mumot HOT 9 CLOSED

This is related to issue #23 - if we close that issue that may be sufficient... expert users can specify parameters directly, non-experts are assumed to want to use the minimal syntax possible.

On the other hand it would be a nice feature to add

from mumot.

Some functionality to do this in partially addressing issue #23 has now been added, within the MuMoTview base class - this might be co-opted, with some error checking (currently missing)

from mumot.

Ideally partial specification of parameters should be possible, which would not provide widgets for those in the corresponding controller - not sure if this works already

from mumot.

I think that experienced users should have the possibility to define the range and step of some widgets. For example the particle speed, or the system size, or the time of the simulation.

We should decide if the user can modify all of them through MuMoTdefault or as input.

Also, at the moment, using MuMoTdefault all rates would have the same initial value, step, and range. Not sure if this is ok.

Commit eef3100
adds the use of the initWidgets parameter for multiagent() and SSA() controllers.
This is only a first solution of initWidgets which could be modified/improved. It might be convenient to follow similar design (e.g. methods that use systemSize should include the desired range in paramNames and paramValues, ---or even better a dictionary #27---)

At the moment, the multiController supports initWidgets only for advanced options.

from mumot.

On multiagent() and SSA() the initWidgets parameter works. We need to decide if the same structure is good for all controllers.

@joefresna I am happy with the initWidgets solution it should be implemented as a private function that we can call from all controller-creating commands, with a few provisos:

• something seems wrong with using initWidgets to specify a standard (e.g. rate) widget; the resulting slider cannot be changed (e.g. add 'mu':[3,0,5]to the dictionary on the test notebook, section SSA and multiagent tests
• including the LaTeX escape character \\ should still lead to the widget being found properly (cf. example immediately above)
• it looks like the defaults for unspecified widgets are taken from MuMoTdefaults? That's perfect.

from mumot.

Hasn't this been refactored to work for all controllers now?

Solved with commit 35d6b11
