+/**
+ * Class FPID
+ * is a Logical Footprint ID and consists of various portions much like a URI.
+ * It is a container for the separated portions of a logical footprint id so they
+ * can be accessed individually.  The various portions of an FPID are:
+ * logicalLibraryName (nick name), footprint name, and revision.  The logical library
+ * name and the footprint name are mandatory.  The revision is optional and currently is
+ * not used.
+ *
+ * Example FPID string:
+ * "smt:R_0805/rev0".
+ *
+ * <p>
+ * <ul>
+ * <li> "smt" is the logical library name used to look up library information saved in the
+ *      #FP_LIB_TABLE.
+ * <li> "R" is the name of the footprint within the library.
+ * <li> "rev0" is the revision, which is optional.  If missing then its
+ *      / delimiter should also not be present. A revision must begin with
+ *      "rev" and be followed by at least one or more decimal digits.
+ * </ul>
