A toy database following this blog, repo

TODOS: [x] def a pager [x] change new_table() to db_open() [] db_open calls pager_open() [x] opens db file [x] inits page cache as nulls [] do we want for now to have it write all the data from file into the table?

[] create get_page() [] it should write a page from file to pager.pages

[] select [] it should handle a "cache miss" [] it should also write the data from file into the new table???? [] insert [] should add a row to table [] should increase rowCount++

[] create db_close() [] flushes page cache to disk (??) [] closes bd file [] frees memory for Pager and Table
