Clarify any confusion around the use of tokens and bits.

[johnnymatthews]

From @rh0delta:

given our confusion around the units of our token, we will need to update the docs to reflect that BITS is the human readable token shorthand
1 token = 0.00000000001 BITS
1 BITS = 10000000000 tokens

Tasks

• Find where we mention tokens and bits.
• Make sure the fit the above details.

@johnnymatthews BITS is locked in ... the smaller unit is less clear. I've heard it definitely not "token".

things being bandied around:

• nanoBits (even though it's 10**-10 Bits, not 10**-9 Bits)
• lilBits
