Current Work In Progress

2019-06-19: Added the index of the sphere to the datatype prot::ND_ImageData, -1 if not a sphere.

2019-06-10: the client will need to sent back to the server some information, after a navigation process. Initially, it has been assumed that this information would be only some images ("sphere differences"). See prot::ND_DiffInfo

To be able to send some more general information, the protocol will implement having the ability to sent also one or several arbitrary text files. Thus prot::ND_DiffInfo now has an additional member (_nbTextFiles) that holds the number of text files sent before/after the images (NOT IMPLEMENTED YET).
