Default use of fractional atoms / tokens

[rigelrozanski]

• By default UI and CLI (for gaia) should use "fractional atoms"
• As per previous discussions with @jaekwon, minimum fraction for atoms should be 10^-8
• still up for discussion I think
• We should allow for the CLI tokens to be input in the fraction as well as non fractional input, aka.

--amount="1000subatoms"

is equivalent to

--amount="0.0001atoms"

and we should allow for both to be input

Can we use 10^-9. Smallest unit is a nanoatom (1 billion nAtoms = 1 Atom).
100 million is weird.

[rigelrozanski]

quarks are roughly 10^-9 in size from an atom - seems like the natural name

Lets go ahead and close this. We have standardized on displaying uatom
