This provides a utility to setup and use a simple event selector. The selection criteria are base on very simple quantities that available once an event directory has been formed. These include things like selection on

1. The number of packets in an event
2. The size of an event
3. The readout mode (single/four-range, zero/non-zero suppressed)
4. The GEM trigger conditions
5. The presence of diagnostic or error blocks

Enumeration Type Documentation

enum _ESS_logic

Identifies the logic used when using multiple selectors as either OR (the default) or AND.

Enumerator:

ESS_LOGIC_K_OR	Use the OR of the select criteria, ie. any
ESS_LOGIC_K_AND	Use the AND of the select criteria, ie. all
