initStrategy will run a series of common initialization functions at the 
beginning of an applyStrategy call.
initStrategy(strategy, portfolio, symbols, parameters = NULL,
  get.Symbols = FALSE, init.Portf = TRUE, init.Acct = TRUE,
  init.Orders = TRUE, unique = TRUE, ...)object of type strategy to initialize data/containers for
portfolio
symbols
named list of parameters to be applied during evaluation of the strategy, default NULL
TRUE/FALSE, default FALSE
TRUE/FALSE, default TRUE
TRUE/FALSE, default TRUE
TRUE/FALSE, default TRUE
TRUE/FALSE, default TRUE
any other passthrough parameters
if TRUE, will call getSymbols 
                         on all symbols included in the symbols vector
if TRUE, will call initPortf 
                         to initialize the portfolio object
if TRUE, will call initAcct 
                         to initialize the account object
if TRUE, will call initOrders 
                         to initialize the order book for this test
not yet implemented, will force a unique portfolio and account name if the portfolio, account, or order book already exist
If used in conjuction with initBySymbol, get.Symbols should be FALSE.
