hotRequire hot-loads modules by extending the system's require() function using the fs.fileWatch() routine (which already comes with node).
Hot-loading means it watches the file for changes and then reloades it's eval'd content into the variable set by the user.

Important: It does NOT rewrite the require(); method rahter than utilizing and extending it.

The file watcher emits catchable events to the process. These events are "modified", "removed" and "reloaded".

var hotrequire = require('./hotrequire.js');

var example = hotrequire('./example.js', function(module) {
	example = module
});

// or

var example = require.hot('./example.js', function(module) {
	example = module
});

console.log(example.message);

npm install hotrequire
