// Description
/*
SnapFile is a library based on SDL and SDL_gfx built to manage an index.

> Why is it relevant to use index ?
Index are commonly used to list files inside a folder. Using index is
relevant because it doesn't rely on a specific exploitation system.
Indeed, listing files in a folder recquires specific libraries which
are different between Windows and Linux.

> What can perform SnapFile ?
SnapFile has many functions do update and read your index. Thanks to SDL, SnapFile
can create windows in order to interact easily with a user, in order to type a file
name or to choose a file from the index.
