- delete auxiliary isogeny coeff file
* add unit tests for wb hashing to bls12-377 g1 and g2
* - Use IsogenyMap struct to specify WB Isogeny for bls12-381 and bls12-377
- Do not use auxiliary constants to define generators of g2_swu_iso curve.
- Update change log
* Bump the Algebra dependencies of bls12_381 and bls12_377 to 0.4.0-alpha.4 so they could use the IsogenyMap struct.

* Drop alpha sub-version in dependancies because it takes the lastest sub version
* Parameters → Config for bls12-377/381 curves
* do cargo fmt
* do SwuIsoParameters → SwuIsoConfig for bls12-377/381
* Adapt to new macro

no actual test vectors yet
* add faster cofactor clearing and tests for g1
* add faster cofactor clearing and tests for g2
parameters of endomorphisms are wrong for now
* add test vectors for bls12-377
* add h_eff to g2 tests for correctness
test
* improve cofactor tests g2

* Fix Bls12-377 scalar group generator
Previously we used 11 as a generator, which has order (p-1)/35.
Now we use 22, which has the right order.
Fixed the two-adic root of unity in accordance with the new generator.
fixes#47
* add the CHANGE LOG
