Originals is a table in the database, it contains one of each type of
thing you wish to be able to clone into the clones table.
MyActiveRecord creates a PHP class for each table you "wrap" it
around, and each row of the table becomes an object of that class when
you request it through MAR.
In short, this line:
if($master = MyActiveRecord::FindById('originals',$original)){
...if it finds a table called 'originals' in your database, will
return the row with the ID matching $original (or false).
