\brief Class to encapsulate a field in an attribute table or data source.

QgsField stores metadata about an attribute field, including name, type

length, and if applicable, precision.

Field types are usually unique to the source and are stored exactly

as returned from the data store.

|
|
* @param prec Field precision. Usually decimal places but may also be
|
|
* used in conjunction with other fields types (eg. variable character fields)
|
|
* @param num Has to be true if field contains numeric values.
