From Compustat data in table "vc4.txt" in the database documentation folder (detailed earlier)
==To Do==
Now that the data we need has been uploaded into the database:
#REDUCE data to US companies
#MATCH data with VC backed companies (Also in the database) to filter companies to only those that have been VC backed
#AGGREGATE '''yearly''' numbers to diagram the following variables over time
##Number of each (IPO, Acquisitions, VC backed...)
##Total Value of all of the transactions (IPO, Acquisitions, VC, Sales and Mkt...)
