Class
    Foam::meshReaders::STARCD
 
Description
    Read pro-STAR vrt/cel/bnd files.
    The protected data in meshReader are filled.
 
    Starting with pro-STAR 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.
