/*! Reads the contents of a field from the stream. It is intended to be used
in conjunction with readFieldHeader and uses the information obtained
by it (\a fieldName, \a fieldTypeName, \a fieldSize ).
If a field is not to be read, but skipped instead, its name can be passed
in the \a excludeFields argument. The string has the format:
"'name1' 'name2' 'name3'", the spaces between the "'" are mandatory.
\param[in] fieldName Name of the field.
\param[in] fieldTypeName Type of the field.
\param[in] fieldSize Size in bytes of the field.
\param[in] excludeFields
\param[out] ptrFieldIt Iterator that points to the PtrFieldInfo structure
that was created, if this is a "pointer field" - only valid if true is
returned.
\return True, if the field is a "pointer field", i.e. a field holding
pointers to other FieldContainers, false otherwise.
