number such as `#1`, `#2`, .. `#_22` for a file with 22 lines. So once I open the file given by `parentKey`, every time as I read a line I create a new key,
let's call it `new_key` using `dupKey(parentKey)`. Then I set `new_key`'s name to `lineNN` (where NN is the line number) using `keyAddBaseName` and
store the string value of the line into the key using `keySetString`. Once the key is initialized, I append it to the KeySet that was passed into the

name `#N` properly saved where it should be according to the `kdb mount` command (in this case, `system/linetest/#N`), and a string value
equal to the contents of that line in the file. The line plug-in repeats these steps as long as it hasn't reached end of file, thus saving the whole file
into a KeySet line by line.
