Synopsis

This class contains some static functions to enable table and column tracing. It maintains a map of table name to table-id.
The following aipsrc variables variables determine if tracing will be done, and if so, which columns and operations will be traced.

table.trace.filename gives the name of the file in which the trace will be written. If empty (default), no tracing will be done. If 'stdout' is given, tracing is done to stdout. If 'stderr' is given, tracing is done to stderr.
table.trace.operation gives the operation to trace. be traced. It can be one or more of:
s: creation of RefTable (selection/sort/iter)
r: reads
w: writes
The default is ''. Note that opening and closing a PlainTable are always traced.
table.trace.columntype gives the types of columns to trace for read and/or write. It can be one or more of:
s: scalar columns
a: array columns
r: record columns
The default is ''.
table.trace.column gives names of additional columns to trace for read and/or write. The names are separated by commas without any whitespace. Each name can be a glob-like pattern.
The default is ''.

If both table.trace.columntype and table.trace.column have an empty value, all array columns are traced.
