 For this project, we will be making use of the venerable **gnuplot** tool. Like many powerful tools we have encountered this semester, we seek only to scratch the surface, and start to familiarize ourselves with the powerful capabilities this resource offers us.

 So this graph will be a nice visual indicator of how you did in various aspects related to the class as a whole.
+=====Spirit of project=====
+The spirit of the project embodies many aspects we've been focusing on throughout the semester:
+  * recognizing patterns to employ effective solutions in problem solving
+  * utilizing concepts and tools covered
+  * demonstrating comprehension of concepts, tools, and problems
+  * employing concepts in knowledgeable and thoughtful manner
+  * following instructions
+  * implementing to specifications
+  * utilizing creativity
+  * being able to control solution via consistent, clear, and organized presentation
+Basically: I want your solution to be the result of an honest, genuine brainstorming process where you have (on your own) figured out a path to solving the problem, you have dabbled and experimented and figured things out, and you can command the concepts and tools with a fluency enabling you to pull off such a feat. Your solution should demonstrate the real learning that took place and experience gained.
+Cutting corners, avoiding work, skimping on functionality, cheating through getting others to do work for you or finding pre-packaged "answers" on the internet violates the spirit of the project, for they betray your ability to pull off the task on your own.
