In this problem, you are working in chemical sales, selling a compound that is used to make batteries. This compound requires a couple of ingredients, which has been stored in structure array "ingredients". You have also been storing some of your past compound orders in anothe rstructure array "orders", but you realize you never noted down how much of each ingredient you use. It is your task to dtermine whether you can solve for the amount of ingredients used for each order, and return the solution, if you can. "ingredients" is a structure array the following information (table) in each of its fields: 
field                                 value
price                     cost of buying this ingredient
mass                     mass of this ingredient
The structure array will contain "N" ingredients elements, all of which are used together to create a singular compound (e.g. if there are 2 elements in "ingredients", then they are used together to create 1 chemical compund)
"order" contains information (table) about some orders you had for this chemical compound: 
field                                value
weight                  total mass of the order
cost                      total cost of fulfilling the order
This structure array contains 1 order for the compound created from combining all the ingredients. With the information you are given, construct a system with the following form: Ax=b where "x" is the amount of each ingredient that you used in the orders. You will try to solve for "x" in this problem. First, you must analyze the system to see what type of solution you will get. There are 3 possibilities: 'Unique', 'Infinite', and 'None'. Once you have determined this, assign this to "num_solutions", and proceed with solving the solution. Notice that "A\b" will still return some value for infinite and no solutions. Tips you have to use: "rref()" cannot be used in the solution in matlab. You are given the following code just fill it in: 
function [num_solutions,solution] = analyzeSales(ingredients, order)
