starting to get some JS working for my form validation.
finally got form validation working for invitee email addrs.
Problem:
    We want to split our flat textarea into an array, using new-line characters
    as the thing to split out.  However, we have seen that newline chars may
    var. Initially we though that "<br>" was always used as the newline char.
	However today we realized that it now seems to be '\n' used as a new line
    char. So how will we deal with this and have it work for both options?

Option 1:
    Sequential Double slpit:
        create tmpArray1 by doing an initial split on <br>,
        iterate through tmpArray1, and split each line based on \n,
            push into a second tmpArray2

        we could be smart about this and first check the original string to
	    see if it has either \n or <br> or both and line things up accordingly?

Option 2:
    Simultaneous double split:
        try and craft a regex that split on either <br> or \n.
        this option is faster in terms of big O notiation (i think) and less
	 	code.

Option 2 appears to have worked (and was done relatively quickly), so checking
in this improvement.
