Update: I removed the DEFAULT_BASETYPE_FACTORY switch because it caused more confusion than it avoided. See Trac #130.
The compile-time symbol DEFAULT_BASETYPE_FACTORY controls whether the old (3.4 and earlier) DDS and DataDDS constructors are supported. These constructors now use a default factory class (BaseTypeFactory, implemented by this library) to instantiate Byte, ..., Grid variables. To use the default ctor in your code you must also define this symbol. If you do choose to define this and fail to provide a specialization of BaseTypeFactory when your software needs one, you code may not link or may fail at run time. In addition to the older ctors for DDS and DataDDS, defining the symbol also makes some of the older methods in Connect available (because those methods require the older DDS and DataDDS ctors.

Check the semantics of the DDS describing a complete dataset. If ALL is true, check not only the semantics of THIS->TABLE, but also recurrsively all ctor types in the THIS->TABLE. By default, ALL is false since parsing a DDS input file runns semantic checks on all variables (but not the dataset itself.

Returns a pointer to the named variable. If the name contains one or more field separators then the function looks for a variable whose name matches exactly. If the name contains no field separators then the funciton looks first in the top level and then in all subsequent levels and returns the first occurrence found. In general, this function searches constructor types in the order in which they appear in the DDS, but there is no requirement that it do so.
