Instructions for Homework 1:

Part 1: Basic C++
-----------------------------
Part 1 of the homework is an excercise in C++. The instructions are
specified in hw1.cpp. Your task is to compute a vector of randomly 
generated integers, compute the mean (i.e., average) of the sample 
and finally, compute the standard deviation. 

Some useful information. 

The C++ reference page for the rand() function is here:
http://www.cplusplus.com/reference/cstdlib/rand/

The formula the uncorrected standard deviation can be found here:
https://en.wikipedia.org/wiki/Standard_deviation#Uncorrected_sample_standard_deviation

Your program should compile with the following command:

g++ hw1.cpp -o hw1

Include a readme file which identifies which parts of the extra credit were completed. 

Part 2: ROS Installation
-----------------------------
For this part, simply install ROS Indigo on your Ubuntu or Mac OS system. Note that
the Max OS ROS is still experimental. It is highly recommended to setup a virtual box with 
Ubuntu 14.04 instead. 

The installation instructions are here:
http://wiki.ros.org/indigo/Installation/Ubuntu
http://wiki.ros.org/indigo/Installation/OSX/Homebrew/Source

Choose the Desktop-Full Install option from the guide. 

To verify your installation, take a screen shot of the terminal window while running "roscore"
