Change the input parameters in the bigData folder to the same approach as in the rest

[JesusGarSan]

I am going to have to do this little by little, but stuff won't work correctly until everythin si changed, so I will use this to track my progress in the version-2-Big_data branch.

I will mark with X the files that I have already updated.

Some functions don't take optional arguments, so I won't be touching those. Same thing goes for funtions in internal/. Since we don't expect users to sue those, I won't change the input parameter structure

I am getting rid of the "Complete call" part of the help, as the example would need to include the value fo the variables.

a proper example will be given in "EXAMPLE OF USE"

All input parameters have been updated and pushed to the version-2-Big_data branch
