Examples

• life cycle
  • deploy contract
  • all participants deposited own tokens until escrow locked up
  • escrow started and all participants starting to unlock own deposited tokens in favor to recipients. Now in any time recipients can withdraw tokens
  • if duration passed - escrow are expired. Now all participants can withdraw own tokens which are not locked (if param swapBackAfterEscrow is true)

Notes:

1. participants/tokens/minimums are combined and linked arrays with the same length. It is means that if participant#1 have address '0x1111...' and want to trade 100 tokens with address '0x2222...' than

participants=['0x1111...']
tokens=['0x222...']
minimums=[100]

if will be added participant#2 with address '0x3333...' and want to trade 200 tokens with address '0x4444...' than

participants=['0x1111...','0x3333...']
tokens=['0x222...','0x4444...']
minimums=[100,200]

and so on 2. swapFrom/swapTo are combined and linked arrays with the same length too
