Executor Design Implementation

##Trade Engine Executor Implementation

The executor will be responsible for processing all of the orders a user makes. It will be constantly checking for new orders, and executing all of the orders it already has.

The system will be made up of four major parts:

• main -- EDIT: We will not need a main since the start/stop script was written in bash instead of Java.
• Makefile -- Responsible for compiling all of the Java code
• Engine -- This will be a giant loop which will run the whole system.
• Executor -- will do all of the actual transactions with orders
• Orders -- Will keep track of order information, and standardize how orders execute.
