/**
* A logical library item identifier and consists of various portions much like a URI.
*
* It consists of of triad of the library nickname, the name of the item in the library,
* and an optional revision of the item. This is a generic library identifier that can be
* used for any type of library that contains multiple named items such as footprint or
* symbol libraries.
*
* Example LIB_ID string:
* "smt:R_0805/rev0".
*
* - "smt" is the logical library name used to look up library information saved in the #LIB_TABLE.
* - "R" is the name of the item within the library.
* - "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.
