Load nodes bound to face into a map of node columns.
| theParam2ColumnMap | - map of node columns to fill |
| theFace | - the face on which nodes are searched for |
| theBaseEdge | - the edge nodes of which are columns' bases |
| theMesh | - the mesh containing nodes |
| bool | - false if something is wrong |
The key of the map is a normalized parameter of each base node on theBaseEdge. This method works in supposition that nodes on the face forms a rectangular grid and elements can be quardrangles or triangles
