API

`caniuse.getSupport(feature)`

y: Since which browser version the feature is available
n: Up to which browser version the feature is unavailable
a: Up to which browser version the feature is partially supported
X: Up to which browser version the feature is prefixed

caniuse.getSupport('border-radius', true)
/*
[ safari: { y: 3.1, x: 4 },
  opera: { n: 10, y: 10.5 },
  ios_saf: { y: 3.2, x: 3.2 },
  ie_mob: { y: 10 },
  ie: { n: 8, y: 9 },
  firefox: { a: 2, x: 3.6, y: 3 },
  chrome: { y: 4, x: 4 },
  and_chr: { y: 39 } ]
*/

`caniuse.isSupported(feature, browsers)`

ask if a feature is supported by some browsers

caniuse.isSupported('border-radius', 'ie 8, ie 9') // false
caniuse.isSupported('border-radius', 'ie 9') // true

`caniuse.find(query)`

search for a caniuse feature name

Ex:

caniuse.find('radius') // ['border-radius']
caniuse.find('nothingness') // []
caniuse.find('css3')
/*

  'firefox 33',
  'chrome 39' ]
