Added Database

I found the prototype SQL CE 3.5 database I created for NyMPH and added it to the solution. I'm hoping to use LINQ for the majority of the queries.

I've implemented IEquatable and IComparable on a couple different domain classes; I will do the same for the rest of them.

I also realized that determining equality between generic List objects takes a bit of code. Right now, I'm comparing item count first (to avoid the cost of full comparison), then iterating through each item until it finds a mismatch.

I could create custom collection classes, but at this point I don't see a need to do so. We'll see how well the 'brute force' item comparison works in terms of performance.

I've also created a spreadsheet to store these changes. It is in /Solution/NyMPH_Classes/NyMPHDevLog.xls.
