RandomNumberGenerators::seedAll from array or file #79

Closed mxmlnkn closed 7 years ago

mxmlnkn commented 7 years ago

A proposition for how to use seedAll with a file of seeds, e.g. created with head -c 1032 > seeds.dat. seedAll now also takes a file name or an std::vector or a simple pointer to an array, with the latter being the most unsafe variant which I only added for legacy. Also moves some includes from the header into the cpp. In general only includes which are needed directly in the header file should be there.

Quite a lot new interfaces! This should make the rng class more flexible and powerful 👍

At the moment, I use almost exclusively the default seedAll() function, @mxmlnkn did you have a particular application for the new interfaces in mind?

mxmlnkn commented 7 years ago

@MartinWenge I needed this in order to get reproducible results with given fixed seeds, so that I can test some changes on the code I'm working on for consistency. Personally I only use the interface which directly reads the seeds from a file, but I guess there might be use cases where they aren't particularly in a file.
