// Example: Calculate divergence (impermanent) loss for a hypothetical position
// ---------------------------------------------------------------------------
// Parameters:
// p - Current price (tokenB per tokenA)
// p_i - Initial price when the position was opened
// p_a - Lower price bound of the range
// p_b - Upper price bound of the range
// depositA - Amount of token A deposited
// depositB - Amount of token B deposited
//
// Here we assume the current price moved to 1.2, it was 1.0 at entry,
// the position range spans from 0.8 to 1.5 and we originally deposited
// 1000 units of token A and 1200 units of token B.
