#!/bin/bash
# create a new file from a template file.
# works using the file extension.
# looks for the template file with same extension in
# templates folder and copies it to the cwd with the passed name

# usage: 
# tmpl tree.cpp
# tmpl reversal.cp.cpp
# tmpl sortQ.java

# this script will replace initc initcpp initjava etc into one script
