prtAlgorithm  Combine prtActions 
 
   ALG = prtAlgorithm creates an empty prtAlgorithm object. prtAction
   objects can be added to the prtAlgorithm object using overloaded
   operators as described below.
 
   ALG = prtAlgorithm(ACTIONOBJ) creates a prtAlgorithm object with the
   prtAction object ACTIONOBJ. The algortihm can be further configured
   using overloaded operators.
 
   Algorithms represent combinations of prtActions.
  
 
   Overloaded operators
  
   +   Inserts a prtAction object at the end of the processing chain
 
   -   Inserts a prtAction object at the beginning of the procesing chain
 
   /   Inserts a prtAction object in parallel with the processing chain
 
   \   Inserts a prtAction object in parallel with the processing
       chain. Note that operators \ and / perform the same operation. The
       only difference is where the actions are displayed when the
       prtAlgortihm is plotted.
