Here is a list of all files with brief descriptions:

containers.hpp	Header file for container metaclass to provide basic compile time containers
eval.hpp	Header file for the eval metaclass to evaluate meta functions and classes
functions.hpp
higher_order_functions.hpp	Header file for nano higher order functions. Higher order functions are functions which satisfy at least one of the following properties: {itemize} { Takes one or more functions as an input } { Outputs a function } {itemize} So this header find contains all functions which fit that definition
list.hpp	Header file for the list metaclass to provide compile time lists
list_functions.hpp
nano.hpp	Header file for the nano library to include all other files
numeric_types.hpp	Header file for static numeric types to use for meta functions
runtime_converter.hpp	Header file for the runtime_converter metaclass which can return runtime containers (like std::vector) from nano containers (mainly lists)
