Initial commit
Merge branch 'master' of https://github.com/wangq79/yoyo-grids
update
mask can make call now, need animation of mask
before using longpress event
refactor and to try longpress, see if it work for quick sweep
use single tap for calling and longpress for info
解决滑动时轻微移位，tapstart出calling mask还是会与scroll整个grid冲突。
改为单点出calling mask，双点出info mask
calling mask打电话实现。点击图标和滑动。
