Added comments; tinkered with white space here and there.

Added comments; tinkered with white space here and there.

Rearranged the code a bit for clarity, without changing functionality.

In doFieldMapperSearch():

- Renamed meta to class_meta, in order to distiguish it from method metadata.
- Rename obj to row_obj, which is more descriptive, and moved its declaration
  closer to its first use.
- Moved the declaration of dedup and links closer to their first uses.

In oilsMakeFieldmapperFromResult():

- Moved the declarations of several variables closer to their first uses.
- Eliminated a couple of unnecessary calls to memset().
