We can now generate part families.

- README: added build prerequisites
- "part name" is now more correctly called "package name"
- changed keyword "part" to "package"
- removed inst_debug and struct inst_ops.debug functions - never really used 
  them anyway
- we can now generate multiple packages from a single file

-The part name is a string of alphanumerical characters. Underscores are
-allowed in the part name as well.
+The package name is a string of printable ASCII characters, including
+spaces.

 Examples:
 
-part "SSOP_48"
-part "0603"
+package "48-SSOP"
+package "0603"
+
+Like in pad names, variables are expanded in package names. This allows
+the generation of multiple packages from a single definition.
