Compiler update (#21)
* added seperate folders for cmd packages.

* Fix netmodes in test + reverse bigint bytes

* glide get deps

* add, sub, mul, div

* booleans

* strings

* binary expressions

* if statements

* function calls

* composite literals (slice, array)

* Added lots of test cases and update readme.
