InsertLib - insert data into file. Delete data from file.

InsertLib is extremely fast, simple and platform independent C++ I/O library that allows you to insert data anywhere in the file or delete data from it without having to copy contents of the file into internal or external memory. Moreover, it can intelligently transform newly inserted or existing offsets in the file without breaking the integrity of existing data after inserting new ones. It creates a perfect illusion of a flexible file.
