Create a regime.portfolios object to support regime switching
optimization. This object is then passed in as the portfolio
argument in optimize.portfolio. The regime is detected and the
corresponding portfolio is selected. For example, if the current
regime is 1, then portfolio 1 will be selected and used in the
optimization.
