compile_main_file v1.0.3

#compile_main_file iterates all subdirectories in a directory writes a module.exports line for each file containd in each sub directories

example

####say you have a directory called "./lib_dir/" ./lib_dir/| | ---|---|--- |TEST1/|
| |file_1.js | |file_2.json |TEST2/|
| |file_3.js CAUTION: provided file_name variable will be overwritten in the main directory, each file must have a unique name; an error will throw if this occurs, your compile file will be broken until you fix the error and rerun

let compile_main_file = require(compile_main_file)
compile_main_file("./lib_dir/", "index")

####index.js will compiled to look like this

module.exports.file_1=require('./lib_dir/TEST1/file_1.js') 
module.exports.file_2=require('./lib_dir/TEST1/file_2.json') 
module.exports.file_3=require('./lib_dir/TEST2/file_3.js')
