/*

This is an experiment in creating a "selenese" parser that drastically

cuts down on the line noise associated with writing tests in HTML.

The 'parse' function will accept the follow sample commands.

test-cases:

    //comment

    command "param"

    command "param" // comment

    command "param" "param2"

    command "param" "param2" // this is a comment

TODO:

1) Deal with multiline parameters

2) Escape quotes properly

3) Determine whether this should/will become the "preferred" syntax

   for delivered Selenium self-test scripts
