Importing other Solidity source files

Solidity allows a source file to import other source files. Here is an example to demonstrate this:

//This statement imports all global symbols from "filename" (and //symbols imported therein) to the current global scope. "filename" can //be an absolute or relative path. It can only be an HTTP URL 
//import "filename"; 

//creates a new global symbol symbolName whose members are all the //global symbols from "filename". 
import * as symbolName from "filename"; 

//creates new global symbols alias and symbol2 which reference symbol1 //and symbol2 from "filename", respectively. 
import {symbol1 as alias, symbol2} from "filename"; 

//this is equivalent to import * as symbolName from "filename";. 
import "filename" as symbolName;
