Class NumberTools

Provides support for converting longs to Strings, and back again. The strings are structured so that lexicographic sorting order is preserved.

That is, if l1 is less than l2 for any two longs l1 and l2, then NumberTools.longToString(l1) is lexicographically less than NumberTools.longToString(l2). (Similarly for "greater than" and "equals".)

This class handles all long values (unlike DateField).
