- now avoid Istream and token mechanism in favour of a simpler string
parser. This makes the code clearer, smaller, robuster.
- provide convenience ge/gt/le/lt static constructors for scalarRange
for using bounds directly with specifying via a string parameter.
- scalarRange, scalarRanges now follow the unary predicate pattern
(using an operator() for testing). This allows their reuse in
other contexts. Eg, for filtering operations:
myHash.filterValues(scalarRange::ge(100));
- remove unused scalarRanges methods that were specific to handling
lists of time values. These were superseded by timeSelector methods
several versions ago.
