	Constructor for creating an empty 4D array of the given dimensions.

	Array4D (MghHeader *mgh_header)
	Constructor for creating an empty 4D array based on dimensions specified in an fs::MghHeader.

	Array4D (Mgh *mgh)
	Constructor for creating an empty 4D array based on dimensions specified in the header of an fs::Mgh. Does not init the data.

Detailed Description

A simple 4D array datastructure, useful for representing volume data.

By convention, for FreeSurfer data, the order of the 4 dimensions is: time, x, y, z.
