Class
    Foam::fileFormats::STARCDMeshReader
 
Description
    Read PROSTAR vrt/cel/bnd files.
    The protected data in meshReader are filled.
 
    Starting with PROSTAR version 4, the files have become easier to read.
    - vertices are space-delimited.
    - the cell format is logical.
    - trimmed and degenerate cells are saved as polyhedral.
    - the boundaries corresponds to cells and their faces.
 
Notes
    - Shell entries are read, yet ignored.
