Tiered Carry in the Venture Capital Model

Small update to the Venture Capital Model:

1. Edited the calculations for tiered carry for each LP class; the calcs for the middle "proceeds applicable for carry" used the distributions from the last period instead of cumulative distributions as of the last period, meaning it did not account for past distributions and any tiered carry for certain returns multiples was not applied. The edit is for all three tiered carry calculations for each LP class.

As always, questions, ask anytime.
