CSCI4235 GOZoom extension of chrome

1,I design a button "on/off" for this extension, if you do not want to
use. Just click the button and you do have to remove.
2,I design two buttons ,"zoomout" and "zoomin" , to change the size for
preview window.
3,I design two models for my extension ,M1 is for whole and original
mini preview of website and M2 is for redesign(including title ,pic and
text). Just switch the button on popup and refresh to change the model.
4,hold  'alt ' for preview reading when mouse leave.
