Material Design Date/Time picker

An implementation of http://www.google.com/design/spec/components/pickers.html in AngularJS and some bootstrap just for helper classes (just the button classes).

Work in progress.

//Using simple bitwise operations:

data[0] = (byte) (width & 0xFF);
data[1] = (byte) ((width >> 8) & 0xFF);
//How it works:

/*
& 0xFF masks all but the lowest eight bits.
>> 8 discards the lowest 8 bits by moving all bits 8 places to the right.
The cast to byte is necessary because these bitwise operations work on an int and return an int, which is a bigger data type than byte. The case is safe, since all non-zero bits will fit in the byte. For more information, see Conversions and Promotions.
