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
{@link Lucene.Net.Documents.DateField}).
