Initial commit of eclipse project.

No idea whether I've got the right directory or the correct .gitignore.
Time will tell...
I've created some java files and added a JAR

This commit doesn't really mean anything is completed, but I felt like
I should commit something. Next I will add some tests.
Added my first tests

And a test runner and stuff. They pass, then again, they don't really
do very much.
Added a test for the BlackScholesOptionPricer

And tidied up the usage of the OptionParameters objects
Created a class to generate random perturbations on parameters

This creates random variations in 3 of the parameters. The randomness is
based on picking from a gaussian distribution with 0-mean and variance
provided to the generator class on construction.

There is also some basic tests (including one which is very flakey and
relies on a random number generator).
Creates a ValueAtRiskComputation class

This class is used to manage a set of computations which could be
distributed across threads or nodes.
Adds a class to run a single-threaded simulation
