Liquidity Provider Token
This token is an ERC20 detailed token with added capability to be minted by the owner. It is used to represent user's shares when providing liquidity to swap contracts.
Only Swap contracts should initialize and own LPToken contracts.

function decimals() external view returns (uint8)
Returns the number of decimals used to get its user representation. For example, if
decimals equals 2, a balance of 505 tokens should be displayed to a user as 5,05 (505 / 10 ** 2). Tokens usually opt for a value of 18, imitating the relationship between Ether and Wei. This is the value {ERC20} uses, unless {_setupDecimals} is called.
