A description of a field in a table.
Field combines a type with the field name, documentation, units, and in some cases, the size of the field.
Specializations for different field types are inherited through FieldBase; see the documentation for those specializations for additional information about particular field types.

Construct a new field.
[in] | name | Name of the field. Schemas provide extra functionality for names whose components are separated by underscores. Field names should be limited to letters, numbers, and underscores. |
[in] | doc | Documentation for the field. Should not contain single-quotes to avoid FITS round-trip problems. |
[in] | units | Units for the field. Should not contain single-quotes to avoid FITS round-trip problems. |
[in] | size | Size of the field as an integer, if appropriate. Field types that accept a size have a FieldBase that is implicitly constructable from an integer, so the argument type should be considered to effectively be int; using FieldBase here allows use to throw when the signature does not match the field type. |
