HDF's Zipa class

Description:
---
This little class allows the easy handling of zip files (for reading only) with the help of php's zip extension.
Can automatically extract everything from a specified zip file, or can read everything in the zip file into an array.

API:
---
string file
array readzip([file])
extracta([path])

file:
The path and name of the zip file. Can be relative.

readzip([file]):
Reads the contents of a zip file into an array. The path and filename is in the index, and the values are the contents of the
files, or false if the index is a directory.
The optional file parameter is supposed to be the same as the public variable "file" in the class.

extracta([path]):
Extracts the zip file, given in the public variable "file", to the given path. Or if not specified, to the current folder.
