/**
* The Exolve code creates only the following names at global scope:
*
* - Exolve
* - createExolve
* - createPuzzle (deprecated).
* - exolvePuzzles
*
* - The most generic way to create a puzzle is with "new Exolve(...)".
* - The createExolve() function is a covenient wrapper.
* - The createExolve() function looks for and calls the function
* customizeExolve() if it exists (passing it the created puzzle).
* - The createPuzzle() function is similar to createExolve(), and
* is deprecated (as the name may conflict with some other code).
* - All HTML ids/class names begin with "xlv"
*/

* This is the global object in which *all* Exolve puzzles rendered on a single
* web page are stored as properties, with the puzzle IDs being the keys.
*/
var exolvePuzzles;
/**
* Constructor to create an Exolve puzzle.
*
* puzzleSpec is a string that contains the puzzle specs in the Exolve plain
* text format.
* containerId is the optional HTML id of the container element in which you
* want to create this puzzle. If empty, the puzzle is created inside
* the element with id "exolve" if it exists (and its id is changed to
* exolve<N> in that case, where <N> is the index of this puzzle among
* all the pages on the page). If containerId is empty and there is no
* element with id "exolve", the puzzle is created at the end of the
* web page.
* customized is an optional function that will get called after the puzzle
* is set up. The Exolve object will be passed to the function.
* provideStateUrl should be set to true if you also want to provide a URL
* that includes the current state and can be bookmarked or shared. Note
* that the puzzle state is always attempted to be saved in local storage.
* visTop should be set to the height of any sticky/fixed position elements
* at the top of the page (normally just 0).
* maxDim If non-zero, use this as the suggested max size of the container
* in px.
* saveState If false, state is not saved in local storage. Useful for
* creating temporary/preview puzzles.
