//! \brief Class for configuring the caching rules
/*!
When partitioning the evaluation graph, the Evaluation Manager uses 
a set of caching rules in order to determine what gets cached.

These rules are made of a pair of one filter and one action. The following
pseudocode highlights the role of cache configuration rules, at scheduling time:

for each node
    for each rule
        if filter(node) is True
        Then 
            call action(node)
        endif

Once registered, filters can be used to create new rules through the 
cacheEvaluator command
