added sample application for debugging

[jgravois]

added a debug folder to the repository with a sample.html file to assist new developers in referencing local, unminified source files.

more sophisticated logic for injecting scripts could be substituted later if desired.

You don't actually need this since you are including the files from /src below.

i've layed down another commit with @patrickarlt 's suggestions.

@tomwayson, i've been chewing on yours and have to admit that i'm torn. i really like the idea of setting things up so that developers don't need to worry about accidently including local changes with an unrelated PR, but at the same time i think its more important to make sure things 'just work' out of the box for developers doing all this for the first time.

perhaps we could split the difference and leave the original source code and include something like this as well?

<!--script src="debug.js">
if you think you'd like to make a pull request at some point in the future 
and you don't want changes here to be included, make a new file called 
'debug.js' in this same folder and store your application logic there.  
we've set up our .gitignore to overlook it.
</script-->

does anyone else have an opinion?

[tomwayson]

Another idea would be to set up .gitignore to ignore all .html files under the debug folder except sample.html. Then just put a comment block in sample.html instructing devs to make a copy of the file before modifying it to test their code. I think that's a simpler way of accomplishing the same thing.

that sounds good to me. i made another change based on @tomwayson 's suggestion and squashed everything down.

happy to make additional tweaks.

Looks good to me @jgravois - thanks!
