PROGRAM NAME
vequal - Informs if two images are equal
DESCRIPTION
vequal
compares two images pixel by pixel and informs if they are equal. In case that the images are equal, it returns a variable affect by the value 1, otherwise this variable is affected by the value 0. An optional constant image can be entered instead of image2.
The two input images must be of the same size and have the same number of data bands. The input images may be of the same or different data types. If the input
images are of different data types, then all input images will be upcast to the highest input image data type.
