Merge pull request #74 from Botinoc/dev

fix an issue with converting large files
changed to the optimal number of elements at a time
it writes 250,000 checkpoint objects at a time, with files containing more than 250,000 checkpoint objects
As a result, everything is converted 
(and it takes ~ 9 minutes if it is a very large file)
