BondingCurve

Represents a bonding curve for a token.

struct BondingCurve has key, drop {
    initial_price_numerator: u128,
    initial_price_denominator: u128,
    growth_constant: u128
}

Name	Type	Description
initial_price_numerator	u128	Initial price numerator for the token.
initial_price_denominator	u128	Initial price denominator for the token.
growth_constant	u128	Growth constant (k) that determines how the price scales with supply.
