/**
* i18n formatting function. Extends Highcharts.format() functionality by
* also handling arrays and plural conditionals. Arrays can be indexed as
* follows:
*
* - Format: 'This is the first index: {myArray[0]}. The last: {myArray[-1]}.'
*
* - Context: { myArray: [0, 1, 2, 3, 4, 5] }
*
* - Result: 'This is the first index: 0. The last: 5.'
*
*
* They can also be iterated using the #each() function. This will repeat
* the contents of the bracket expression for each element. Example:
*
* - Format: 'List contains: {#each(myArray)cm }'
*
* - Context: { myArray: [0, 1, 2] }
*
* - Result: 'List contains: 0cm 1cm 2cm '
*
*
* The #each() function optionally takes a length parameter. If positive,
* this parameter specifies the max number of elements to iterate through.
* If negative, the function will subtract the number from the length of the
* array. Use this to stop iterating before the array ends. Example:
*
* - Format: 'List contains: {#each(myArray, -1) }and {myArray[-1]}.'
*
* - Context: { myArray: [0, 1, 2, 3] }
*
* - Result: 'List contains: 0, 1, 2, and 3.'
*
*
* Use the #plural() function to pick a string depending on whether or not a
* context object is 1. Arguments are #plural(obj, plural, singular).
* Example:
*
* - Format: 'Has {numPoints} {#plural(numPoints, points, point}.'
*
* - Context: { numPoints: 5 }
*
* - Result: 'Has 5 points.'
*
*
* Optionally there are additional parameters for dual and none:
* #plural(obj, plural, singular, dual, none). Example:
*
* - Format: 'Has {#plural(numPoints, many points, one point, two points,
* none}.'
*
* - Context: { numPoints: 2 }
*
* - Result: 'Has two points.'
*
*
* The dual or none parameters will take precedence if they are supplied.
