/*

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
