Remarks
A MeasureSpec encapsulates the layout requirements passed from parent to child. Each MeasureSpec represents a requirement for either the width or the height. A MeasureSpec is comprised of a size and a mode. There are three possible modes: <dl> <dt>UNSPECIFIED</dt> <dd> The parent has not imposed any constraint on the child. It can be whatever size it wants. </dd>
<dt>EXACTLY</dt> <dd> The parent has determined an exact size for the child. The child is going to be given those bounds regardless of how big it wants to be. </dd>
<dt>AT_MOST</dt> <dd> The child can be as large as it wants up to the specified size. </dd> </dl>
MeasureSpecs are implemented as ints to reduce object allocation. This class is provided to pack and unpack the <size, mode> tuple into the int.
