note: this was awesome!
caller vs caller_locations(1, 1) vs __LINE__
Print line number where "Function [is] Called" instead of "Function Definition".
caller_locations(1, 1) standard post Ruby 2.0
caller if pre Ruby 2.0

Why caller_locations(1,1)? Its much faster than caller(), source: https://stackoverflow.com/questions/5100299/how-to-get-the-name-of-the-calling-method

note: a good read

nice: http://ruby-doc.org/docs/keywords/1.9/Object.html#method-i-__LINE__
note: the above link was also useful for a note in external repo: #1
Reason: "defined?"

This will be added to the readme.md:
In any language when approaching this problem these steps must be discussed:

These definitions must be understood:
Function Definition vs Prototype/Function Declaration vs Calling the Function

re-built from:http://www.tutorialspoint.com/ansi_c/c_using_functions.htm
had to refresh the ol'e "c skills". 😄

additional: what internals allow ruby to do this?

1. what exactly is it doing?
2. how efficient will the solution be? examples like callerlocaition is faster than caller

next, we are going to build it in C and Java!
