Avg Cap Table

Update to the Venture Capital Model, Average Cap Table:

• Major expansion of the model to account for multiple entry points (i.e. first checks at different stages). This is a common request that is easy to add in simple ways, hard to do in an elegant way, and this expansion took a lot of extra math. Edited `Get Started`` to add a number of new lines that now allows you to allocate capital to different first check strategies, set follow-ons per round per first check strategy, and the model will handle capital allocation, number of deals, and returns automatically. It's hard to emphasize how much extra math this took under the hood to get right, but I think it's still a fairly straightforward and easy to use model even with the new inputs and expanded structure. Enjoy!
