Great work, thanks.

part14.html's phrase "treats f as an object" had me wonder why part03.html omits object as a data type. May be good to note e.g. "Tables, functions, threads, and (full) userdata values are objects: variables do not actually contain these values, only references to them." -- http://www.lua.org/manual/5.3/manual.html#2.1.

Re: http://tylerneylon.github.io/video-scripts/learn_lua_in_an_hour/part13.html:

1. Typo: > funciton bad() return false, 'was bad' end
2. Define how the two error categories referred differ. Is it whether or not a stack trace is dumped?
