"""
Given an open csv file , read the file according to the
specification and return all the elevation maps stored within the file.


IMPORTANT: the given argument to the function is an OPEN file ,
you will not need to open it again, and can begin performing standard file
operations on it.


The file will be structured as follows:
- The first line will contain one number, which will denote the number
of elevation maps stored within this file.
- The next n lines will contain two numbers each, "r" and "c", which
are the number of rows and columns of each elevation map.
- The rest of the data will then be comprised of the elevation map
data, which will follow one another in sequence, with no spaces in
between.


For an example, see "sample_data.csv".
