// The programming goals of Split.js are to deliver readable, understandable and

// browser compatibility without additional requirements, graceful fallback (IE8 is supported)
// and very few assumptions about the user's page layout.

// The main function to initialize a split. Split.js thinks about each pair
// of elements as an independant pair. Dragging the gutter between two elements
// only changes the dimensions of elements in that pair. This is key to understanding
// how the following functions operate, since each function is bound to a pair.
//
// A pair object is shaped like this:
//
// {
// a: DOM element,
// b: DOM element,
// aMin: Number,
// bMin: Number,
// dragging: Boolean,
// parent: DOM element,
// isFirst: Boolean,
// isLast: Boolean,
// direction: 'horizontal' | 'vertical'
// }
//
// The basic sequence:
//
// 1. Set defaults to something sane. `options` doesn't have to be passed at all.
// 2. Initialize a bunch of strings based on the direction we're splitting.
// A lot of the behavior in the rest of the library is paramatized down to
// rely on CSS strings and classes.
// 3. Define the dragging helper functions, and a few helpers to go with them.
// 4. Define a few more functions that "balance" the entire split instance.
// Split.js tries it's best to cope with min sizes that don't add up.
// 5. Loop through the elements while pairing them off. Every pair gets an
// `pair` object, a gutter, and special isFirst/isLast properties.
// 6. Actually size the pair elements, insert gutters and attach event listeners.
// 7. Balance all of the pairs to accomodate min sizes as best as possible.
