BigNeuroVec

A class representing a sparse four-dimensional brain image that is backed by a disk-based big-matrix. BigNeuroVec objects are designed for efficient handling of large-scale brain imaging data that do not fit into memory. This class inherits from the NeuroVec, AbstractSparseNeuroVec, and implements the ArrayLike4D interface.
