 * @notice
 *   This contract calculates suitable tick ranges to fully deposit liquidity asset.
 *   It maintains two strategies for unipilot vaults
 *   1) Base order => For depositing in-range liquidity
 *   2) Range order => To distribute remaining assets behind or ahead of base order ticks,
 *   so that users liquidity does not abruptly goes out of range
 *   @dev These ranges are named as follows.
 *   Base => upper and lower ticks for main range to deposit
 *   Ask => Upper and lower ticks ahead of the current tick and base upper
 *   Bid => Upper and lower ticks behind the current and base lower
