Plot Interface Refactoring about massdash

[singjc]

I kind of like the config interface to avoid having too many parameters in the method call, unless we use **kwargs to pass parameters directly to the plotting (bokeh figure/ plotly figure) interfaces (which may be limited).

I like the idea of having the plotting methods also directly part of the structs.

I don't mind the config its just don't really like how some parameters are not relevant for certain plots. Maybe the plot config should be directly parameters of the respective plotters? not a general thing? I am not sure will have to think about it more

Some refactoring was done in the #106 More refactoring might need to be done?
