Option: dateStatusFunc
A function that receives a JS Date object and returns a boolean or a string. This function allows one to set a certain CSS 
class to some date, therefore making it look different. 
If it returns true then the date will be disabled. 
If it returns false nothing special happens with the given date. 
If it returns a string then that will be taken as a CSS class and appended to the date element. 
If this string contains disabled then the date is also disabled (therefore is like returning true) but with your own custom style.
