class Pagy
# Default :breakpoints
VARS[:breakpoints] = { 0 => [1,4,4,1] }
# Helper for building the page_nav with javascript. For example:
# with an object like:
# Pagy.new count:1000, page: 20, breakpoints: {0 => [1,2,2,1], 350 => [2,3,3,2], 550 => [3,4,4,3]}
# it returns something like:
# { :items => [1, :gap, 18, 19, "20", 21, 22, 50, 2, 17, 23, 49, 3, 16, 24, 48],
# :series => { 0 =>[1, :gap, 18, 19, "20", 21, 22, :gap, 50],
# 350 =>[1, 2, :gap, 17, 18, 19, "20", 21, 22, 23, :gap, 49, 50],
# 550 =>[1, 2, 3, :gap, 16, 17, 18, 19, "20", 21, 22, 23, 24, :gap, 48, 49, 50] },
# :widths => [550, 350, 0] }
# where :items is the unordered array union of all the page numbers for all sizes (passed to the PagyResponsive javascript function)
# :series is the hash of the series keyed by width (used by the *_responsive helpers to create the JSON string)
# :widths is the desc-ordered array of widths (passed to the PagyResponsive javascript function)
