v75: Bugfix for remote HDFS systems

Bugfix to allow users to provide hdfs hostname in their urls.

v72: Addressing code review comments

Moves format check to front.

v68: Bugfix for receiving arguments

In certain shell environments, arguments given to CLIKickoff can come as
many strings instead of just one. This fix marshalls all arguments into
one string and operates on a garbage-in, garbage-out principle. Because
CLIKickoff is only intended to be called programmatically from
Spark-Launch, this fix should suffice.

v64

Updating documentation for adding workloads

v62

Updating examples with smaller parameters

v60

Changes from code review

v57: Benchmark output now optional

When users don't specify any " benchmark-output" in their config file
there will simply be no output.

v55

Fixing bad links

v54: Stripping README, improving docs site

This commit moves all project documentation from the README to the docs
site. This will hopefully be more user-friendly and prevent the README
documentation from getting stale.

This commit also adds a media page with the Spark-Bench presentation, a
guide for contributing to Spark-Bench, improvements to the Quickstart
guide, addition of an Installation guide, and a guide for using SBT in
the context of the project.

v52

Adding issue template for Github Issues
