Now log are managed by the std log, did a custom log to print either
into a file or into the default io strout.
The plan is to create a scope in each file and log depending of stuff,
can also use it in library I think, if should still base by the custom
function.
Next step is logging a lot of stuff a bit everywhere.
Added the datatype date, time and datetime
Moved all custom erros to a single file
Cleaned code to be more readable and created some small utils
Other stuffs that I dont recall. Basically preparing for the
relationship implementation
Removed the loop for the CLI, now just take some argument using the
binary. May come back to while loop if I need to keep like the file
engine between session. To run query in parallel.
Moved printError and send to utils and removed duplicate of them.
Organized FileEngine better.
Put the function that convert string to value in a seperate file.
Fix some synthax and make it smaller. Removed unused functions too
