FTP object: FTP client wrapper

===== BASIC DOCUMENTATION FOR FTP_OBJECT CLASS =====

0.- INTRODUCTION AND EXTENTS

This class is designed as an easy wrapper for FTP connection management, allowing 
for encapsulated management of FTP commands and results.

1.- BASICS OF OPERATION

The class is a wrapper for all common (non blocking support not yet there, but i'll be adding it someday)

PUBLIC INTERFACE:

	This function just lists every file/dir (no distinction yet...) in the current directory

* function dirlist() ;
	Listing remote directory contents:
		NO PARAMS

	Putting a file in the remote server:
		$filename-> filename (in local drive and will be used as well on remote)
		$mode-> Transfer mode 0->binary 1->ascii
	Copy $filename to server with the same name, returning TRUE on success or FALSE otherwise
	
* function get($filename,$mode=0)
	Retrieving a file from the remote server:
		$filename-> filename (in remote drive and will be used as well on local)
		$mode-> Transfer mode 0->binary 1->ascii
	Copy $filename to local directory with the same name, returning TRUE on success or FALSE otherwise

2.- Future releases and WIP

	I'll be adding new features, like non-blocking transfers and extras for dirlists... I have also 
	a small JavaScript based IDE for ftp management, but I don't think I'll be working too actively
	on it, as I have plenty of work to do... any suggestions and comments will be appreciated.

3.- Additional notes

	This class requires various levels of permissions on both filesystems, local and remote, to work
	fully, so check permissions if strange errors ocurr.
	
	CHMOD commands have not been added but will be possibly added soon.
