[development] Create files programmatically

[nan wich]

I already have a functioning module that creates some CSV files for my 
customer. 
It appears now that they are going to be expanding the file inventory, so time 
to get more creative. Does anyone know of a module that allows them to input a 
list of fields they want and creates a table with that schema? There will 
pretty 
much only be int and varchar fields, so I don't need to handle everything. My 
module can already largely be otherwise driven by the schema.
