To express the price of bitcoin relative to ether, we must use a ratio of the number of wei to a satoshi.

+A simple design is to use `x` wei : 1 satoshi. Hence, for a call to `getPrice` when 32.32 ETH : 1 BTC (Jun 2019),
the value 323 200 000 000 wei is returned.
However, if 1 wei is worth more than 1 sat, then the price can no longer be accurately encoded. This scenario of a 'flippening',
when 1 ether becomes worth 10,000,000,000x as much as 1 bitcoin, we find unlikely in the very short-term.
-Rather than prematurely optimize, incorporating a 2 integer ratio of `x` satoshi to `y` wei and changing the call semantics,
