* parameters:
* questions: array of arrays. inner arrays are arrays of strings, where each string represents a prompt
* for the user to respond to.
* labels: array of arrays of arrays. inner most arrays are label markers for the slider, e.g. ["Strongly Disagree", "Neutral", "Strongly Agree"].
* need one inner array for every question that is part of the trial. middle arrays group questions together.
* intervals: array of arrays. inner arrays are how many different responses the user can select from, e.g. 5, one for each question.
* show_ticks: graphically show tick marks on the slider bar to indicate the response levels.
* data: optional data object
