Structure

PROLEAD's structure consists of two directories.

1. The inc folder contains all header files (.hpp) encompassing the function declarations.
2. The src folder contains all source files (.cpp) encompassing the function definitions.

All files related to the evaluation of hardware circuits are stored in the Hardware subdirectories (inc/Hardware and inc/Hardware) while the Util subdirectory stores all files that declare and define generic functions.
