Issue 56 (extendable land unit area)

[vidhya001]

Issue 56 wants the user to give the land area variable rather than calculation it from the function already present in the FLINT code. I was able to figure out where the area function is called and separated that part and added it into a new function. I need to look at the JSON part and then assign that JSON value instead of the existing function Signed-off-by: Sree Vidhya [email protected]
