PositionalRanges should support spanning entire possibility

This works for everything except reality using -inf and inf (float values), but reality rejects non int values. Instead, it should allow whatever number format as long as it is a whole number or +/- infinity. When serving json, drop the .0 from the end and serve as an int or +/- inf

• [x] Allow +/- inf for range values
• [x] Ensure reality is served without the .0
• [x] Allow Infinity and -Infinity flags for range values in json
• [x] Allow single number for PositionalRanges in json (process into same val for high and low) (Not Doing)
• [x] Allow ALL flag for PositionalRanges in json (process into low=-inf, high=+inf) (Not Doing)
• [x] Update API Spec

Decided that using an ALL flag to simplify the -inf -> inf is not necessary. Similarly, passing a single value for a range is not worth the complexity it adds.
