Loading multiple Json file

[ampotos]

Currently dynStruct.py can only process the Json file made by the data gatherer on at a time.

Adding an option to load more than one file at a time and another option to add a file into the serialized data (or the db file if implemented) can be usefull for program which don"t have the same behaviour on every run.

But when doing that, a way to say in wht run the block was recorded must be found. And in the case of adding a file maybe rerun the structure recovery to use the nex context provided can be a good thing.
