Field is the base class for a field of a statistics structure.

Convert a camel-cased string to a set of space separated, lower case words.
Preserves uppercase acronyms, so 'launchVDOErrorCount' becomes
'launch VDO error count'.

Create a new field.
:param name: The name of the field
:param cType: The class representing the C representation for this field
when sampled via an ioctl
:param **kwargs: Keyword arguments which may be:
available: Specifies python code to apply to other
fields of the parent structure to decide
whether this value is available. Defaults
to True.
derived: Specifies python code to apply to other
fields of the parent structure to derive the
value of this field. Defaults to None.
display: If not True, this field will not be included
in labeled output. Defaults to True.
label: The label for this field. If unspecified, the
label will be derived from the field name.
length: if > 1, indicates this field is an array of
the specified cType, otherwise is is a
scalar. Defaults to 1.
