// simple variant on TestAat.java
// This calls Pat to load an ARC/INFO PAT file into an array of objects,
// processes them, and writes a report.
// The first argument is the name of an arc cover.
// The second argument is the name of a data item, such as X-COORD
// This can be called from the command line: e.g. java TestPat upolyb X-COORD
// or from another class, such as 
// Exceptions are written to standard error.
// Caveats:
//  Error handling is neither complete nor elegant
//  This will not recognize PAT files which are not stored as "pat.adf".
//  Class Arccheck assumes a specific item list for the arcs being checked. 
//  A commented-out block of code for writing to the PAT is included only for
//  your edification.
