Helper classes for reading individual lines from stacked timeseries images
The classes, and instances of these classes, are designed to decrease the number of relatively expensive file open calls that are made unnecessarily if reading from the same files over and over. When using GDAL, for example, tests have shown that unnecessary opening and closing of images and image bands is slower compared to keeping the file reference and opening the files only once.
