Sorting algorithm for Magic: the Gathering colours. Sorts programatically: guilds and shards in perfect sequence and order every time. Uses first position sorting for wedges. Was surprised to see this hadn't been done before, so I wanted to save someone the heartache of trying.
for example:
wubrgSort.optimiseSequence(['blue','white']) will return/mutate the correct ['white','blue'] sequence.
in cases where you have a collection of objects with the colors property on it (where it is an array of [colors]), you can sort them out:
[ {colors: sultai}, {colors: naya},{colors: simic},{colors: selesnya}, {colors: jund}, {colors: jeskai},{colors: boros},{colors: gruul}, {colors: esper},{colors: abzan},{colors: golgari},{colors: rakdos}, {colors: temur}, {colors: grixis},{colors: izzet},{colors: dimir}, {colors: mardu}, {colors: bant},{colors: orzhov},{colors: azorius} ].sort(wubrgSort.sortCombinations);
would return azorius to selesyna, orzhov to simic, esper to bant and abzan to temur in predictable, logical order.
