Detailed Description

template<class A>
class CutList< A >

Templated CutList class to contain a group of cuts.

The CutList is typically instantiated with a vector of Accept objects, although additional cuts may be added with the 'add' method. Cuts may be applied in one of two ways, determined by the 'mode' parameter: ALL: Always apply every cut UNTIL_FAIL: Apply cuts until the first one fails The 'accept' method applies the cuts and keeps internal count of how many times it is called.
