RocketDatabase:

--------------------------------------------------------------------------
   Load the properties for a rocket: mS, thrust, ISP, exhaust velocity.
   If the vehicle is not hard-coded in this database it will load the csv
   database and check there. The default database is LVDatabase.csv

   Since version 1.0
--------------------------------------------------------------------------
   Form:
   d = RocketDatabase( name, file )     Get data for a case
   list = RocketDatabase                List all case names
