Use cases and interesting example projects

[HarryR]

In order to make it easier for people to use EthSnarks, we need to create more example applications that demonstrate the functionality and provide a basis for people to build applications on.

Example applications:

• Batch signature verification
• Ring signatures
• Pyramid scheme / Fomo 3d?
• Dutch auction
• Passing lots of data from EVM to a zkSNARK circuit
• Proof of group membership
• Semaphore implementation
• Reputation system
• Neural network
• Blind exchange
