Mint

Mint creates the next token id and assigns it to \`to\`. Only sequential minting is supported (id is returned via the Mint event).

Transfer

Transfer moves token \`id\` from the caller to \`to\`. The caller must own the token (approvals are cleared on transfer).

Approve

Approve grants \`spender\` the right to transfer token \`id\`. Only the current owner may approve.

ownerOf

approvedOf

balanceOf

balanceOf returns how many tokens \`owner\` holds.

exists

exists reports whether token \`id\` has been minted (and not since moved away).

totalSupply

totalSupply returns the number of tokens in circulation. There is no burn, so the highest id ever assigned is the count.

OwnerOf

BalanceOf

BalanceOf is the exported read-only accessor for balanceOf.

TotalSupply

TotalSupply is the exported read-only accessor for totalSupply.

Render

Render displays collection metadata and a token -> owner table.
