Detailed Description
This is the class from which the user should derive her own algorithmic variables.
Note that such an object cannot be constructed (it has pure virtual methods), only objects with types derived from BCP_var_algo can be created. Such objects are constructed either directly by the user or by the unpacking functions of the BCP_xx_user classes.
