Gates
Sets of gates may be defined here
for later use in the commands section
through which to filter the event-by-event data.
If a data word being tested matches a particular gate condition
it is said to pass that particular gate.
Bitmask, 1D and 2D gates are stored as 8-bit lookup maps.
Elliptical gates are stored as lists of coordinates and axes.
When a sortword value is tested against a gate in the commands section
it will pass either zero or one of the gates in the map.
The gate number passed will be stored in the reserved variable
GATE
