Special Card - Largest Army Claim by Player + Transfer [Medium]

[rogersanick]

In Settlers of Catan, the first player to achieve the largest army (with 3+ knights) is able to claim a token representing a certain number of victory points. We need to enable them to do so in Settlers of CorDan as well!

This issue depends on #2

To complete this task we need to:

// States

1. Create a Largest Army state

// Flows

1. Create a flow to claim the largest army
2. Create a flow to transfer ownership of the largest army from one player to another

// Contracts

1. Create a contract to govern the largest army state

// BONUS POINTS

• Mitigate the denial of largest army attack - where the first player to claim the largest army refuses totransfer ownership of it later.
