WIP

Note, there is no reason to build Hera. One can use the releases: https://github.com/ewasm/hera/releases

Trying to use the release of hera..

Also, issue persists even when not using Docker.

Of it must be some missing symbol issue. (The new EVMC loader is capable returning proper error messages, but the geth PR is not updated yet.)

Okay, I think this should be mergeable now that it's in a state where other WRC20 implementations can make use of the tests.

I want to add more tests but C is currently failing transfer:

wrc20-examples/truffle/test/ERC20.test.js

Lines 33 to 43 in 25674c0

	it('Should be able to send a balance between two accounts', () => {
	const receivingAddress = '0x85ea6adbac1ca7e16c6c9f59115ce2d370b0b358';
	const receivedAmount = new BN('1000', 10)
	return instanceA.transfer.call(PrefundedAddress, receivedAmount).then(res => {
	return instanceA.balance.call(receivingAddress).then(balance => {
	console.log("balance is ", balance)
	assert((new BN(balance, '16')).eq(receivedAmount), util.format("actual account balance (%s) != expected amount(%s)", new BN(balance, '16'), receivedAmount));
	})
	})
	})

This also needs an updated README and probably renaming/cleanup.
