/**
* 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>
