Add Sqlite support to Exponent

Challenges

Multiple versions of RN

Secure isolation

Is it ok to prefix database path with current experience’s name?

fork https://github.com/exponentjs/exponent

note: keep running `tools_public/gulp` or you will get an error: exponent requires an internet connection.

Clojurescript on Exponent

Why

1. Simple made easy

It’s much easier than Using React Native with Clojurescript, so beginners don’t have to be nervous!

a. Single entry

No separate iOS or Android projects, do support separate iOS or Android Javascript modules.

b. Only dance with Clojurescript, no native.

Solve the externs

1. Recursively scan source-path/.cljs[cljc]* to find all unused vars and interops.

Idea from https://gist.github.com/Chouser/5796967, currently exponent-cljs-template uses this way.

2. Transform all interop to aget

So closure compiler will not rename the properties or calls under advanced compilation.

repos use this idea:

1. cljs-oops
2. fence
