Evaluate one rule subelement (pass/fail)

A rule element may contain another rule, a node attribute expression, or a date expression. Given any one of those, evaluate it and return whether it passed.

[in]node_hashNode attributes to use when evaluating expression
[in]roleResource role to use when evaluating expression
[in]nowTime to use when evaluating expression
[out]next_changeIf not NULL, set to when evaluation will change

Returns
TRUE if expression is in effect under given conditions, else FALSE
