Detailed Description

This is used to create PLMD::Action objects that are run with some set frequency.

Any PLMD::Action that does not inherit from PLMD::Action is only run when some other Action requires the output from it in order to run. This class is used in PLMD::Bias Action which drives the execution of other Action's. Action's of this kind are executed with a fixed stride which is specified on the directive line with a STRIDE= keyword

only pass an ActionWithValue to this routine if you know exactly what you are doing.
