Algorithms to create x_init automatically to the zero image

[paskino]

Could we have a default x_init automatically set to the zero image of appropriate size? We almost always use that and would save the user from worrying about allocating one. Of course should allow to pass an x_init if desired.

BTW functions do not have a domain defined? @jakobsj @epapoutsellis

In FISTA we only pass functions so it's not possible at the moment to know what is the domain and hence to create the right initialisation data container

I've been thinking about the same thing, really algorithms only deal with functions so would need to check function domain. Maybe leave as is for now and think about it whether we want function domains

it is my fault, it can be done but we need to change many files.

[paskino]

it seems that this requires a bit more thought. I'll take this issue off the symposium milestone.
