LONG - The "LongFloat" Library

Provides "infinite-precision" math with numbers in string form.

E.g.  What's the square root of 123456789.123456789, accurate to 30
decimal places?

30 'DIGITS' STO
"123456789.12345789" FSQR --> "11111.1110661111109694305549817"

If 'DIGITS' does not exist, 20 is assumed.  'DIGITS' must be less
than 10000.  Large settings may cause inordinate run times.
