* Class LIB_TABLE

* This class owns the <b>library table</b>, which is like fstab in concept and maps
* logical library name to the library URI, type, and options. It is heavily based on
* the SWEET parser work done by Dick Hollenbeck and can be seen in new/sch_lib_table.h.
* A library table has the following columns:
* <ul>
* <li> Logical Library Name (Nickname)
* <li> Library Type, used to determine which plugin to load to access the library.
* <li> Library URI. The full URI to the library source, form dependent on Type.
* <li> Options, used for as yet to be defined information such as user names or passwords
* </ul>
* </p>
* <p>
* The Library Type can be one of:
* <ul>
* <li> "file"
* <li> "ftp"
* <li> "http"
* </ul>
* </p>
* <p>
* For now, the Library URI types needed to support the various types can be one of those
* shown below, which are typical of each type:
* <ul>
* <li> "file://C:/mylibdir"
* <li> "ftp://kicad.org/partlib/trunk"
* <li> "http://kicad.org/partlib"
* </ul>
* </p>
* <p>
* The library table is built up from several additive entries (table fragments), and the
* final table is a (conceptual) merging of the table fragments. Two anticipated sources
* of the entries are a personal table saved in the KiCad configuration and a project
* resident table that resides in project file. The project footprint table entries are
* considered a higher priority in the final dynamically assembled library table. An row
* in the project file contribution to the library table takes precedence over the personal
* table if there is a collision of logical library names. Otherwise, the entries simply
* combine without issue to make up the applicable library table.
