 I got bored with having to use complicated checking and stuff when working with files and arrays in C, so I implemented a new `file_t` struct which can load the contents of a file into a dynamically allocated array (yes, there is an implementation of those here as well... (`vector_t` struct)). The struct also stores the number of lines the file has.
 
-Also, I managed to come up with an implementation of a Python-like list (a vector of vectors of any type interpreted as just one vector). Quite handy, I'd say. The `list_t` struct is what you want to use when working with lists.

 The difference between a `vector_t` and a `list_t` is that a vector can only be of one type, whereas a list can have values of any type inside it (in this context, any means types defined in this library and default types in C).
