Recursively delete entries containing `what` before entry pointed to by `which`
merge.list

Method to merge two lists Matches names of each list element and combines any sub-elements
evens

Shortcut functions to return the odd and even values from a vector
readdir

Loads all readable files in a directory into a list, with names according to the filenames
