reuse callbacks, default table/column names, & unique combinations

[mechinn]

The library is great but to integrate it into a project I am working on I needed to add unique combinations and that I could restart the loaders to working with callbacks more than once.

While adding that I made it so that I could use the variable names and class names as the column names and table names respectively by default if no argument is given to @column or @table

I hope that you and the rest of your library's users find these modifications useful

I would appreciate it if this were three separate pull requests as the changes aren't dependant on each other, this makes it easier to merge one change while discussing and changing parts of another.

Regarding the changes.

• Having implicit table/column names has been proposed before and i state the reasons for not wanting this in pull request #35.
• Changing initLoader() -> restartLoader() seems like a valid change. Split it into a seperate pull request and i'll merge it :+1:
• Unique combinations should definitely be added. I am not so sure about the proposed Api but open a specific pull request for this feature and we can discuss it there.
