Algorithm clonability should be explicitly set by Alg author
The clonability of an Algorithm is best decided by the Algorithm author, and should not be a Property of the Algorithm that can be changed at run time.
This MR removes the IsClonable
Property of Algorithms, and changes
it into a protected bool that derived Algs can modify. We should consider
whether the default should be true
or false
. It is currently set to true
for the sake of convenience.
If an Alg is not clonable, then its cardinality is automatically set to 1 during sysInitialize.
