Add a single entry point for install
Instead of writing:
$ mkdir ucoin-v0.12
$ curl -kL https://github.com/ucoin-io/ucoin/releases/download/v0.12-beta3/ucoin.tar.gz | tar xz -C ucoin-v0.12
it would be better to have something like:
$ wget -qO- http://ucoin.io/install.sh | bash
that would install ucoin with last version at: ~/.ucoin
, just like nvm is doing.
