## Detailed Description

Defines a generally defined Field for STEP data : can be used either in any kind of entity to implement it or in free format entities in a "late-binding" mode A field can have : no value (or derived), a single value of any kind, a list of value : single or double list.

When a field is set, this defines its new kind (Integer etc..) A single value is immediately set. A list of value is, firstly declared as for a kind (Integer String etc), then declared as a list with its initial size, after this its items are set Also it can be set in once if the HArray is ready

## Constructor & Destructor Documentation
