Detailed Description

Abstract base class for input modules.

Input modules should read the contents of #fldFile in the Process() function and populate the members of #m. Typically any given module should populate Mesh::expDim, Mesh::spaceDim, Mesh::node and Mesh::element, then call the protected ProcessX functions to generate edges, faces, etc.
